\func{void}{BuildWhereClause}{\param{wxString \&}{pWhereClause},
\param{int }{typeOfWhere}, \param{const wxString \&}{qualTableName=""},
\param{bool }{useLikeComparison=false}}
Constructs the portion of a SQL statement which would follow the word 'WHERE'
in a SQL statement to be passed to the datasource. The returned string
does NOT include the word 'WHERE'.
\wxheading{Parameters}
\docparam{pWhereClause}{Pointer to storage for the SQL statement retrieved.
To be sure you have adequate space allocated for the SQL statement, allocate
DB\_MAX\_STATEMENT\_LEN bytes.}
\docparam{typeOfWhere}{The type of where clause to generate. Can be one of
two values: DB\_WHERE\_KEYFIELDS or DB\_WHERE\_MATCHING.}
\docparam{qualTableName}{{\it OPTIONAL}. Prepended to all base table
column names. For use when a FROM clause has been specified with the
\helpref{wxDbTable::SetFromClause}{wxdbtablesetfromclause},
to clarify which table a column name reference belongs to. Default is "".}
\docparam{useLikeComparison}{{\it OPTIONAL}. Should the constructed WHERE
clause utilize the LIKE comparison operator. If false, then the '='
operator is used. Default is false.}
\wxheading{Remarks}
This member function allows you to see what the SQL WHERE clause looks like
that the ODBC class library builds. This can be used for debugging purposes
if you are having problems executing your own SQL statements.
If using 'typeOfWhere' set to DB\_WHERE\_MATCHING, any bound columns currently
containing a NULL value are not included in the WHERE clause's list of
columns to use in the comparison.
