Searches the dataset for a specified record and makes that record the current record.
Call Locate to search a dataset for a specific row and make it the current row.
KeyFields is a string containing a semicolon-delimited list of field names on which to search.
KeyValues is a variant that specifies the values to match in the key fields. If KeyFields lists a single field, KeyValues specifies the value for that field on the desired row. To specify multiple search values, pass a variant array as KeyValues, or construct a variant array on the fly using the VarArrayOf routine. For example:
with ADOTable1 do Locate('Company;Contact;Phone', VarArrayOf(['Sight Diver', 'P', '408-431-1000']), [loPartialKey]);
Options is a set that optionally specifies additional search latitude when searching on string fields. If Options contains the loCaseInsensitive setting, then Locate ignores case when matching fields. If Options contains the loPartialKey setting, then Locate allows partial-string matching on strings in KeyValues. If Options is an empty set, or if KeyFields does not include any string fields, Options is ignored.
Locate returns true if it finds a matching row, and makes that row the current one. Otherwise Locate returns false.
