INSERT Function
The INSERT function returns a character string where a specified number of characters within
the character string have been deleted beginning at a specified start position and then another
character string has been inserted at the start position.
INSERT is a Neoview SQL extension.
INSERT (char-expr-1, start, length, char-expr-2)
char-expr-1, char-expr-2
are SQL character value expressions (of data type CHAR or VARCHAR) that specify two
strings of characters. The character string char-expr-2 is inserted into the character string
char-expr-1. See
start
specifies the starting position start within char-expr-1 at which to start deleting length
number of characters. After the deletion, the character string char-expr-2 is inserted into
the character string char-expr-1, beginning at the start position specified by the number
start. The number start must be a value greater than zero of exact numeric data type and
with a scale of zero.
length
specifies the number of characters to delete from char-expr-1. The number length must
be a value greater than or equal to zero of exact numeric data type and with a scale of zero.
length must be less than or equal to the length of char-expr-1.
Examples of INSERT
•
Suppose that your JOB table includes an entry for a sales representative. Use the INSERT
function to change SALESREP to SALES REP:
UPDATE persnl.job
SET jobdesc = INSERT (jobdesc, 6, 3, ' REP')
WHERE jobdesc = 'SALESREP';
Now check the row you updated:
SELECT jobdesc FROM persnl.job
WHERE jobdesc = 'SALES REP';
