TParam.SetData Method

Copies a new value for the parameter in physical database format from Buffer.

Pascal

procedure SetData(Buffer: Pointer);

C++

__fastcall SetData(void * Buffer);

Description

Use SetData to set the value of a parameter from a buffer that contains data in the physical database format. The GetData method of a TField object fetches data in the physical database format. Borland Database Engine API calls can also provide data in physical database format.

Note: When the DataType property is ftUnknown, ftBytes, ftVarBytes, ftAutoInc, ftBlob, ftGraphic, ftFmtMemo, ftParadoxOle, ftDBaseOle, or ftTypedBinary, SetData raises an EDatabaseError exception. For BLOB fields, use the SetBlobData method instead.
