Name: ODBC::DATABASE-COLUMN-INFO
Section:
Odbc Database Operators
Synopsis:
<odbc::database-column-info DBVAR TABLE FIELDNAME>
Description:
Returns an alist of properties of a column of a table. Example:
((NAME . "realname")(LENGTH . "30")(TYPE . "GSQL_CHAR")(IS_UNIQUE . "")(IS_NULLABLE . "true")(QUALIFIER . "")(OWNER . "")(TYPENAME . "")(PRECISION . "0")(SCALE . "0")(RADIX . "0")(TABLE . "accounts"))
This is actually implemented by fetching information on *all*
columns and selecting the specified one. It is thus more
efficient, if you are looking for info on several columns, to use
database-columns-info, and get all the column information in a
single array.
