ESRI.ArcGIS.AnalysisTools Namespace > Select Class : where_clause Property

An SQL expression used to select a subset of features by attributes. The syntax for the expression is slightly different, based on the data you're querying. If you're querying ArcInfo coverages, shapefiles, INFO tables, or dBASE tables, field names must be enclosed in double quotes in the SQL expression: "MY_FIELD". If you're querying personal geodatabase data, enclose fields in square brackets: [MY_FIELD]. If you're querying ArcSDE geodatabase data or data in an ArcIMS feature class or ArcIMS image service sublayer, don't enclose fields: MY_FIELD. Personal geodatabase uses '*' and '?' as string wild cards rather than the '%' and '_' used by all other formats. Personal geodatabase - '[CNTRY_NAME] = 'Canada'' If you're querying file based or multiuser geodatabase data - "'CNTRY_NAME' = 'USA'" or '"CNTRY_NAME" = \'USA\'' (In, Optional)
