This Oracle tutorial explains how to use the Oracle / PLSQL CONCAT function with syntax and examples. The Oracle / PLSQL CONCAT function allows you to concatenate two strings together. UPDATE PROMO_CAPTURE_MONTHLY SET DELFLAG = '@ Request.selectITEM~' WHERE JOBNBR = '@ Request.jobNBRlhidden~'; The selectITEM checkbox, which is added under a Data Table column in the Analysis Grid, has a checked value set to 1, unchecked value set to 0 and Default Value set to @ Data.DELFLAG~ (which is 0 initially).
Unfortunately you can't update a substring - but you can update the complete field. Assuming we have to update the field "BEINFA" (20 Bytes character) of file TESTFILE. We intend to update only position 8 to "X".
