vIf the first argument is UCS2 graphic data and the result is mixed data, the result length is (2.5*(n-1)) + 4.

The third argument, if specified, must be a valid SBCS or mixed CCSID. If it is a SBCS CCSID, the first argument cannot be a DBCS-either or DBCS-only string.

The result of the function is the character string that would result if the character string expression was assigned to a varying-length host variable with a length attribute of n, where n is the length attribute of the result. If the length attribute of the argument is greater than the length attribute of the result, truncation is performed and no warning is returned.

The result data type is VARCHAR.

If the ccsid (third argument) is not specified:

vIf the first argument is SBCS character, then the result is SBCS character. The CCSID of the result is the same as the CCSID of the first argument.

vIf the first argument is mixed (DBCS-open), DBCS-only, or DBCS-either then the result is mixed. The CCSID of the result is the same as the CCSID of the first argument.

vIf the first argument is non-UCS2 graphic, then the result is mixed. The CCSID of the result is the associated mixed CCSID of the DBCS CCSID.

vIf the first argument is UCS2 then the CCSID of the result is the job CCSID. If the job CCSID is mixed, then the result type is mixed. If the job CCSID is SBCS, then the result is SBCS character.

If the ccsid is specified:

vThe result is dependent on the specified CCSID. If ccsid is a SBCS CCSID, then the result type is SBCS character. If ccsid is a mixed CCSID, then the result type is mixed character.

vThe CCSID of the result is the ccsid.

If the first argument can be null, the result can be null; if the first argument is null, the result is the null value.

Following are examples of using VARCHAR to convert from CHARACTER to VARCHAR and UCS-2 GRAPHIC to VARCHAR:

RESCHAR varchar(char1,10,37)

where char1 is a character field to be converted 10 is the length of the output variable

37 is the ccsid of the output variable

RESUCS2 varchar(ucs2,8,37)

where ucs2 is a UCS-2 graphic field to be converted 8 is the length of the output variable

37 is the ccsid of the output variable

Following are examples of using VARCHAR to convert from CHARACTER to VARCHAR and UCS-2

GRAPHIC to VARCHAR:

 

 

RESCHAR

varchar(char1,10,37)

where char1 is a character field to be

 

 

converted, 10 is the length of the

 

 

output variable, and 37 is the CCSID

 

 

of the output variable

RESUCS2

varchar(ucs2,8,37)

where ucs2 is a UCS-2 graphic field

 

 

to be converted, 8 is the length of the

 

 

output variable, and 37 is the ccsid of

 

 

the output variable
