The Lookup method scrolls |
Tue, Mar 31 2009 1:43 AM | Permanent Link |
"Roy Jonker" | It seems that the TTable Lookup method scrolls the table.
Delphi Help says: "Description: Call Lookup to search for a record in the dataset in which specified fields contain specified values and return other field values from the found record. Unlike other dataset search methods, Lookup performs its search without moving the record pointer of the dataset. This is useful when doing data validation on a record's data while the record is still in edit or insert mode." Lookup method really belongs to TBDEDataset. Is the implementation different for EDB?

TEDBTable.Lookup doesn't move the record pointer too, if that is what you are asking. -- Fernando Dias [Team Elevate] |

Why do you think Lookup is moving the cursor? Roy Lambert [Team Elevate] |

"Roy Jonker" | I should have been a bit clearer: when called during an Insert (same table
as the Lookup) it cancels the Insert. Maybe that is asking a bit much ... Roy "Roy Lambert" <roy.lambert@skynet.co.uk> wrote in message news:63500431-00DB-4224-BC55-426F7C1CB228@news.elevatesoft.com... > Roy > > > Why do you think Lookup is moving the cursor? > > Roy Lambert [Team Elevate] > |

Same table, same cursor or same table, different cursor? Roy Lambert [Team Elevate] |

"Roy Jonker" | Same table, same cursor. Which, as I wrote before, may be asking a bit much.
