get_sql_from_value

Description:

public abstract string get_sql_from_value (Value? value)

Creates a new string which is an SQL representation of the given value, the returned string can be used directly in an SQL statement.

For example if value is a G_TYPE_STRING, then the returned string will be correctly quoted. Note however that it is a better practice to use variables in statements instead of value literals, see the <link linkend="GdaSqlParser.description"> GdaSqlParser</link> for more information.

If the value is NULL or is of type GDA_TYPE_NULL, or is a G_TYPE_STRING and get_string returns null, the returned string is "NULL".

this	an object which implements the DataHandler interface
value	the value to be converted to a string, or null

the new string, or null if an error occurred
