The POSITION function returns the integer value of the first location of a search character string within a target character string. If the search string does not occur in the target character string, zero is returned. A string of blanks is a valid search string. The syntax of the POSITION function is:
POSITION('search string'/colname IN 'target string'/colname)
In the following example, the position of a literal string in a column is returned in a select statement:
“SELECT NAME POSITION('CICS' IN RECOV_PROC) FROM SYSTEMS”
This statement returns the following variables for the POSITION column:
In the following example, the position of a column value in a literal value is used in the where clause of a select statement:
“SELECT NAME FROM SYSTEMS WHERE POSITION( NAME IN 'XYZ IMS') > 0”
Because the NAME column value of IMS does occur in the literal value specified, the NAME='IMS' row is selected.
