Hello, It seems simple, however, there are important elements: The data type is NUMBER(10, 0). A Refresh is being performed, and an Append or Edit is not being done to the TFDTable. Yesterday, I was able to isolate the problem and it replicates as follows: FDTable.Active: =True; FDTable.IndexName:= 'TABLE_A1'; FDTable.Refresh; FDTable.IndexName:= 'TABLE_A2'; FDTable.Refresh;//Error occurs here I found that the problem only occurs, if the field "COL3" exists in an index where it is sorted as DESCENDING: CREATE INDEX "MyDB"."TABLE_A3"(COL1, COL2, COL3 DESC) ..; The paleative solution is to remove the "TABLE_A3" index, or remove it from being DOWN. Ideally, FireDAC should always work, however, this is not the case when there are indexes with descending fields on the table in ORACLE.

Hello. I have an error when doing: FDTable.Refresh; The error is the following: The above error does not always occur, and sometimes the problem is removed when I rename the table in ORACLE (RENAME TABLE ..) to any other name. My table is like the following: CREATE TABLE "MyDB"."TABLE_A"( COL1 VARCHAR2(1 CHAR) DEFAULT(' ') COLLATE USING_NLS_COMP NOT NULL ENABLE, COL2 NUMBER(10, 0) NOT NULL ENABLE, COL3 NUMBER(10, 0) NOT NULL ENABLE //other columns CONSTRAINT TABLE_A1 PRIMARY KEY (COL1, COL2, COL3) ) DEFAULT COLLATION USING_NLS_COMP I have the following "Map Rule": with MapRules.Add do begin PrecMin:= 10; PrecMax:= 10; ScaleMin:= 0; ScaleMax:= 0; SourceDataType:= dtBCD; SourceDataType:= dtInt32; end; I have observed in "TFDPhysOracleCommand.CreateDefineInfo", that when I activate (TFDTable.Active:= True), the value of the precision of this column is 10, however, when it fails, the value that is taken in the precision (variable " iPrec") is equal to 38. Information: Any suggestion? Thanks in advance.
