Converting a String to HEX in SQL

Solution 1:

Can you use Cast and the fn_varbintohexstr?

SELECT master.dbo.fn_varbintohexstr(CAST(SomeStringColumn AS varbinary)) 
FROM SomeTable

I'm not sure if you have that function in your database system, it is in MS-SQL.

I just tried it in my SQL server MMC on one of my tables:

SELECT     master.dbo.fn_varbintohexstr(CAST(Addr1 AS VARBINARY)) AS Expr1
FROM         Customer

This worked as expected. possibly what I know as master.dbo.fn_varbintohexstr on MS-SQL, might be similar to informix hex() function, so possibly try:

SELECT     hex(CAST(Addr1 AS VARBINARY)) AS Expr1
FROM         Customer

Solution 2:

The following works in Sql 2005.

select convert(varbinary, SomeStringColumn) from SomeTable
