SQLCA.SQLWARN Settings Immediately after DATABASE Executes (ESQL/C)

Immediately after DATABASE executes, you can identify characteristics of the specified database by examining warning flags in the sqlca structure.

If the first field of sqlca.sqlwarn is blank, then no warnings were issued.
The second sqlca.sqlwarn field is set to the letter W if the database that was opened supports transaction logging.
The third field is set to W if database is an ANSI-compliant database.
The fourth field is set to W.
The fifth field is set to W if database converts all floating-point data to DECIMAL format. (System lacks FLOAT and SMALLFLOAT support.)
The seventh field is set to W if database is the secondary server (that is, running in read-only mode) in a data-replication pair.
The eighth field is set to W if database has DB_LOCALE set to a locale different from the DB_LOCALE setting on the client system.
