For every view you create, DB2 stores descriptive information in several catalog tables. The following actions occur in the catalog after the execution of CREATE VIEW: A row is inserted into SYSIBM.SYSTABLES. A row is inserted into SYSIBM.SYSTABAUTH to record the owner's privileges on the view.

Creating a scalar function. To create a scalar function, you use the CREATE FUNCTION statement as follows: NOTE: There are a few important considerations to make regarding the DB2 SUBSTR function: The start location must be an integer between 1 and the length or maximum length of the string, depending upon whether the string is fixed or varying-length.

You put this in a function (UDF): set index = posstr(string, '-'); if (index <> 0) then -- Recursive case set pre = substr(string, index-1); set pos = POSSTR . Similar to the LOCATE function, but with the arguments reversed . POSSTR returns the position of the first occurrence of the second argument within the first argument. For example .
