A SQLSTATE structure is used in conjunction with ct_diag to retrieve SQL state information, if any, associated with a Client-Library or server message.
An application must declare a SQLSTATE structure as an array of 6 characters.
The sqlstate fields of the CS_CLIENTMSG and CS_SERVERMSG structures are treated identically to SQLSTATE, except that they are defined as 8 bytes. The last 2 bytes are ignored.
