Commitment control (COMMIT)

Specifies whether SQL statements are run under commitment control.

*CHG or *UR: Specifies the objects referred to in SQL ALTER, CALL, COMMENT ON, CREATE, DROP, GRANT, LABEL ON, RENAME, and REVOKE statements and the rows updated, deleted, and inserted are locked until the end of the unit of work (transaction). Uncommitted changes in other jobs can be seen.
*CS: Specifies the objects referred to in SQL ALTER, CALL, COMMENT ON, CREATE, DROP, GRANT, LABEL ON, RENAME, and REVOKE statements and the rows updated, deleted, and inserted are locked until the end of the unit of work (transaction). A row that is selected, but not updated, is locked until the next row is selected. Uncommitted changes in other jobs cannot be seen.
*ALL or *RS: Specifies the objects referred to in SQL ALTER, CALL, COMMENT ON, CREATE, DROP, GRANT, LABEL ON, RENAME, and REVOKE statements and the rows selected, updated, deleted, and inserted are locked until the end of the unit of work (transaction).

Severity level (ERRLVL)

Specifies whether the processing is successful, based on the severity of the messages generated by the processing of the SQL statements. If errors that are greater than the value specified for this parameter occur during processing, no more statements are processed and the statements are rolled back if they are running under commitment control.

10: Statement processing is stopped when error messages with a severity level greater than 10 are received.
0-40: Specify the severity level to be used.

Date format (DATFMT)

name: Specify the name of the library to be searched.

Print file (PRTFILE)

Specifies the printer device file to which the RUNSQLSTM printout is directed. The file must have a minimum length of 132 bytes. If a file with a record length of less than 132 bytes is specified, information is lost.

Qualifier 1: Print file

*CURLIB: The current library for the job is searched. If no library is specified as the current library for the job, the QGPL library is used.
name: Specify the name of the library where the printer file is located.

Allow copy of data (ALWCPYDTA)

Specifies whether a copy of the data can be used in a SELECT statement.

*OPTIMIZE: The system determines whether to use the data retrieved directly from the database or to use a copy of the data. The decision is based on which method provides the best performance. If the Commitment control (COMMIT) parameter is not *NONE, the Allow blocking (ALWBLK) parameter should be set to *ALLREAD, when possible, for best performance.
*YES: A copy of the data is used only when necessary.
*NO: A copy of the data is not used. If a temporary copy of the data is required to perform the query, an error message is returned.

Allow blocking (ALWBLK)

Specifies whether the database manager can use record blocking and the extent to which blocking can be used for read-only cursors.

*ALLREAD

Rows are blocked for read-only cursors. All cursors in a program that are not explicitly able to be changed are opened for read-only processing even though there may be EXECUTE or EXECUTE IMMEDIATE statements in the program.

Specifying *ALLREAD:

Allows record blocking for all read-only cursors.
Can improve the performance of almost all read-only cursors in programs, but limits queries in the following ways:
- The Rollback (ROLLBACK) command, a ROLLBACK statement in host languages, or the ROLLBACK HOLD SQL statement does not reposition a read-only cursor when *ALLREAD is specified.
- Dynamic running of a positioned UPDATE or DELETE statement (for example, using EXECUTE IMMEDIATE), can not be used to update a row in a cursor unless the DECLARE statement for the cursor includes the FOR UPDATE clause.

*NONE

Rows are not blocked for retrieval of data for cursors.

Specifying *NONE:

Guarantees that the data retrieved is current.
May reduce the amount of time required to retrieve the first row of data for a query.
Stops the database manager from retrieving a block of data rows that is not used by the program when only the first few rows of a query are retrieved before the query is closed.
Can degrade the overall performance of a query that retrieves a large number of rows.

*READ

Records are blocked for read-only retrieval of data for cursors when:

*NONE is specified for the Commitment control (COMMIT) parameter, which indicates that commitment control is not used.
The cursor is declared with a FOR READ ONLY clause or there are no dynamic statements that could run a positioned UPDATE or DELETE statement for the cursor.

SQL rules (SQLCURRULE)

Specifies the semantics used for SQL statements.

*DB2: The semantics of all SQL statements will default to the rules established for DB2. The following semantics are controlled by this option:
Hexadecimal constants are treated as character data.
*STD: The semantics of all SQL statements will default to the rules established by the ISO and ANSI SQL standards. The following semantics are controlled by this option:
Hexadecimal constants are treated as binary data.

Decimal result options (DECRESULT)

Specifies the maximum precision, maximum scale and minimum divide scale that should be returned for result data types. The specified limit only applies to numeric (zoned) and decimal (packed) data types used in arithmetic expressions and in SQL column functions AVG and SUM.

Element 1: Maximum precision

31: The maximum precision (length) that should be returned for the result data types is 31 digits.
63: The maximum precision (length) that should be returned for the result data types is 63 digits.

Element 2: Maximum scale

31: The maximum scale (number of decimal positions to the right of the decimal point) that should be returned for the result data types is 31 digits.
0-63: Specify the maximum scale (number of decimal positions to the right of the decimal point) that should be returned for the result data types. The value can range from 0 to the maximum precision.

Element 3: Minimum divide scale

0: The minimum divide scale (number of decimal positions to the right of the decimal point) that should be returned for both intermediate and result data types is 0.
0-9: Specify the minimum divide scale (number of decimal positions to the right of the decimal point) that should be returned for both intermediate and result data types. The value cannot exceed the maximum scale. If 0 is specified for the maximum scale, minimum divide scale is not used.
