Returns a TRUE or FALSE value that indicates whether the string requires double quotes around it when it is used as a SQL
identifier. This function formulates a request to the database server to determine if quotes are needed. Relevant information
is stored in the sqlcode field.
There are three cases of return value/code combinations:
return = FALSE, sqlcode = 0
The string does not need quotes.
return = TRUE
The sqlcode is always SQLE_WARNING, and the string requires quotes.
return = FALSE
If sqlcode is something other than SQLE_WARNING, the test is inconclusive.
