How to cast or convert numeric to varchar data type on sybase?-CodePudding

DECLARE
    @k numeric,
    @acc numeric
SET
    @k = 651393561522 ,
    @acc = 1231234560
WHILE (@k < 651393563552)
    BEGIN
        SET @k = @k   1 ,
            @acc = @acc   1
        insert into recipients (id, client_id, inn, name, bic, bill, version)
        VALUES(@k, 1, @acc, 'clientid'  cast(@k as varchar), 300335, 'bill' cast(@acc as varchar), 1)
    END

Have such errors:

[42000][257] Implicit conversion from datatype 'NUMERIC' to 'VARCHAR' >is not allowed. Use the CONVERT function to run this query.

[42000][257] Implicit conversion from datatype 'INT' to 'VARCHAR' is >not allowed. Use the CONVERT function to run this query.

CodePudding user response：

The error messages mention implicit conversion errors so this would tend to rule out the explicit conversions being performed by the cast() calls.

This leaves us with datatype mismatch issues for the other columns/values; OP will want to doublecheck the datatypes of the recipients columns:

the 1st error message mentions numeric to varchar and since the only numeric values are @k and @acc, I'm guessing either the id or inn column is defined as varchar
the 2nd error message mentions integer to varchar and since Sybase (ASE) treats 1 and 300335 as integers, I'm guessing either the client_id, bill or version column is defined as varchar
