Decode in control file in sql loader

Is there a roundabout way of doing that? Anand, July 13, - am UTC. Hi Tom, As i had mentioned earlier it is just a hypothetical situation May be like finding out what is the format in which the date is stored in July 13, - am UTC. NO, without a format, anything is fair game isn't it. No there "shouldn't" be a way. Tom, i've got a load of data which we've got the 9i external table definitions for, but we need to load this into an 8i database. Note, the 9i and 8i databases are seperate clients and we have no mechanism for database links etc.

January 08, - pm UTC. Susan, May 04, - pm UTC. Tom, We have asc files that have dates in this format: I added mmddyy to your package array. I thought everything was working nicely, but, I noticed that it's transposing certain dates -- for eg.

I haven't fully diagnosed it, but, I think the problem occurs when the day begins with a zero. Any thoughts? Thanks for the help. May 04, - pm UTC. Susan, May 05, - am UTC. Susan, May 05, - pm UTC. May 05, - pm UTC. Thanks Tom! Hi Tom, The above information was very helpful.

In my need the coloumn is in timestamp with local time zone. Please guide me how to do that. May 25, - am UTC. Thanks Lamya. June 02, - pm UTC. If so , how to fix it in UNIX? Thanks for your help as aways,. August 13, - pm UTC. UTF8 to the same as database character set, it succeeded. August 16, - pm UTC. Please correct me if i'm wrong. September 02, - am UTC. Splendid vrd, February 26, - pm UTC. Hi Tom, The discussion is splendid.

However, I am facing a rather peculiar problem. I have a delimited file and have to load its data into 9 different tables, for which I have written 9 different control files.

I assure you, I'm using only 10 records as a sample , but stil get these errors. I don't know what's wrong. February 27, - am UTC. How are we doing? Please help us improve Stack Overflow. Take our short survey. Stack Overflow for Teams — Collaborate and share knowledge with a private group.

You have two approches here: 1 Either you process your infile first and replace X by 1, y by 2, z by 3. Then use SQL loader using when condition to check what vendoe id is it and amount column should take what value.

Hi Ramesh, this is a very good writeup! Would be great if you could write something on this too. HI all, I wanted too load mulitple files into the same tables from different ctl files for test work. The problem is i need to be able too identify the different files loaded in de database.

For example : file1. Thanks for giving such valuable examples. Could you please give one example of control file to upload data in a file and then call a procedure to implement some logic and populate main table. Very nice article. Better understandable format. Explained well. We need more examples like this. I have a flatfile notepad , which has data not in order, fields separated by space, that too not orderly separated.

Between fields there is space, but not ordered one. I tried using field terminated by space but, it has taken the entire row of data from notepad as a single column data in table, remaining fields in table are empty. It would be great if anyone can solve my problem.

After executing this below command from oracle forms6 sqlldr80 does not resume back to form, it remains there cursor blinking after Commit point reached — logical record count It started from last week only, never happend before… dont know what made to act like this?

Is there any way to terminate the control file i mean to exit sqlldr and come back to DOS prompt? It is not coming out of sqlldr mode… but inserting data is done perfectly.. I have a different scenario. I have a table with 5 columns, c1, c2, c3, c4, c5 and a csv file has 6 columns, a,c1,c2,c3,c4,c5.

I would like to load c1 to c5 columns data from the csv file to c1 to c5 columns in the table. Can we skip columns any columns from csv or can we map csv columns to table columns in the loader control file? Hi, How to insert alternate rows into two different tables. I mean to insert 1,3,5,7,9,…… Records into Table1 and 2,4,6,8,10,…..

Is there any option to build control to achieve this? Please let me know. Thank You. Thanks for great article, Is there any way to write control file with update statements. I want to update few records. Is there any way around?

If I have too many columns which is not a feasible option to write each and every… how can this be done?? Can anyone please suggest. Article was really helpful. Easy and simple examples to understand. Please post such articles on daily basis. Thanks for the wonderful sharing. I am stuck here. I am trying to upload a flat file rows in an oracle db but i am getting an error. Thank you! So is there any alternate way to do this in shell scripting.

You helped lot of people to understand what actually the sql loader is and how it works…Thanks from all of us…Keep post your articels.. It would be very kind if you help me as you have done it in recent past. So I want to know the following questions to be answered:. Describe in Detail the following: I: Trailing by nullcols.

II: Optionally closed by. I have updated oracle version to 11g. But while executing vb file it is taking 10g version. Please tell me where can i get path to oracle while executing vb file. The default filename is the name of the datafile, and the default file extension or file type is. A discard filename specified on the command line overrides one specified in the control file.

If a discard file with that name already exists, it is either overwritten or a new version is created, depending on your operating system. A filename specified on the command line overrides any discard file that you may have specified in the control file.

The following list shows different ways you can specify a name for the discard file from within the control file:. An attempt is made to insert every record into such a table.

Therefore, records may be rejected, but none are discarded. You can limit the number of records to be discarded for each datafile by specifying an integer:. When the discard limit specified with integer is reached, processing of the datafile terminates and continues with the next datafile, if one exists. You can specify a different number of discards for each datafile. Or, if you specify the number of discards only once, then the maximum number of discards specified applies to all files. Oracle9i Database Globalization Support Guide.

The fastest way to load shift-sensitive character data is to use fixed-position fields without delimiters. To improve performance, remember the following points:.

The following sections provide a brief introduction to some of the supported character encoding schemes. Multibyte character sets support Asian languages. Data can be loaded in multibyte format, and database object names fields, tables, and so on can be specified with multibyte characters.

In the control file, comments and object names can also use multibyte characters. Unicode is a universal encoded character set that supports storage of information from most languages in a single character set. Unicode provides a unique code value for every character, regardless of the platform, program, or language. A character in UTF-8 can be 1 byte, 2 bytes, or 3 bytes long. Multibyte fixed-width character sets for example, AL16UTF16 are not supported as the database character set.

This alternative character set is called the database national character set. Only Unicode character sets are supported as the database national character set. However, the Oracle database server supports only UTF encoding with big endian byte ordering AL16UTF16 and only as a database national character set, not as a database character set. When data character set conversion is required, the target character set should be a superset of the source datafile character set.

Otherwise, characters that have no equivalent in the target character set are converted to replacement characters, often a default character such as a question mark? This causes loss of data. If they are specified in bytes, and data character set conversion is required, the converted values may take more bytes than the source values if the target character set uses more bytes than the source character set for any character that is converted.

This will result in the following error message being reported if the larger target value exceeds the size of the database column:. You can avoid this problem by specifying the database column size in characters and by also using character sizes in the control file to describe the data. Another way to avoid this problem is to ensure that the maximum column size is large enough, in bytes, to hold the converted value.

Normally, the specified name must be the name of an Oracle-supported character set. However, because you are allowed to set up data using the byte order of the system where you create the datafile, the data in the datafile can be either big endian or little endian.

Therefore, a different character set name UTF16 is used. It is possible to specify different character sets for different input datafiles. If the control file character set is different from the datafile character set, keep the following issue in mind. To ensure that the specifications are correct, you may prefer to specify hexadecimal strings, rather than character string values. If hexadecimal strings are used with a datafile in the UTF Unicode encoding, the byte order is different on a big endian versus a little endian system.

For example, "," comma in UTF on a big endian system is X'c'. On a little endian system it is X'2c00'. This allows the same syntax to be used in the control file on both a big endian and a little endian system. For example, the specification CHAR 10 in the control file can mean 10 bytes or 10 characters. These are equivalent if the datafile uses a single-byte character set. However, they are often different if the datafile uses a multibyte character set.

To avoid insertion errors caused by expansion of character strings during character set conversion, use character-length semantics in both the datafile and the target database columns. Byte-length semantics are the default for all datafiles except those that use the UTF16 character set which uses character-length semantics by default.

It is possible to specify different length semantics for different input datafiles. The following datatypes use byte-length semantics even if character-length semantics are being used for the datafile, because the data is binary, or is in a special binary-encoded form in the case of ZONED and DECIMAL:. This is necessary to handle datafiles that have a mix of data of different datatypes, some of which use character-length semantics, and some of which use byte-length semantics.

The SMALLINT length field takes up a certain number of bytes depending on the system usually 2 bytes , but its value indicates the length of the character string in characters. Character-length semantics in the datafile can be used independent of whether or not character-length semantics are used for the database columns.

Therefore, the datafile and the database columns can use either the same or different length semantics. Loads are interrupted and discontinued for a number of reasons. Additionally, when an interrupted load is continued, the use and value of the SKIP parameter can vary depending on the particular case.

The following sections explain the possible scenarios. In a conventional path load, data is committed after all data in the bind array is loaded into all tables.

If the load is discontinued, only the rows that were processed up to the time of the last commit operation are loaded. There is no partial commit of data. In a direct path load, the behavior of a discontinued load varies depending on the reason the load was discontinued. This means that when you continue the load, the value you specify for the SKIP parameter may be different for different tables.

If a fatal error is encountered, the load is stopped and no data is saved unless ROWS was specified at the beginning of the load. In that case, all data that was previously committed is saved. This means that the value of the SKIP parameter will be the same for all tables.

When a load is discontinued, any data already loaded remains in the tables, and the tables are left in a valid state. If the conventional path is used, all indexes are left in a valid state. If the direct path load method is used, any indexes that run out of space are left in an unusable state. You must drop these indexes before the load can continue. You can re-create the indexes either before continuing or after the load completes. Other indexes are valid if no other errors occurred. See Indexes Left in an Unusable State for other reasons why an index might be left in an unusable state.

Use this information to resume the load where it left off. To continue the discontinued load, use the SKIP parameter to specify the number of logical records that have already been processed by the previous load.

At the time the load is discontinued, the value for SKIP is written to the log file in a message similar to the following:. This message specifying the value of the SKIP parameter is preceded by a message indicating why the load was discontinued. Note that for multiple-table loads, the value of the SKIP parameter is displayed only if it is the same for all tables. However, there may still be situations in which you may want to do so.

At some point, when you want to combine those multiple physical records back into one logical record, you can use one of the following clauses, depending on your data:. In the following example, integer specifies the number of physical records to combine.
