Hi everyone. I want to create a program that can connect to a SQLServer database, access a table and create a local copy on HFSQL.
I have already written a code that works but its performance is very low, any suggestions?
My actual code:
Procedure SQLtoHFSQL(cServer, cUser, cPass, cBase, cTableName)
ConnectionNum is int ConnectionNum = SQLConnect(cServer, cUser, cPass, cBase,"OLEDB",hOledbSQLServer)
IF ConnectionNum <> 0 THEN cQuery is string = "select * from " + cTableName IF SQLExec(cQuery, "oQry") THEN aColumnas is array of strings aCol is array of strings nCol is int = 1 oFile is File Description oFile..Name = "oData" oFile..Type = hFileNormal
oItem is Item Description nTipo is int StringToArray(SQLColumn("oQry", True),aColumnas,CR) nColumnas is int = SQL.NbCol WHILE nCol <= nColumnas StringToArray(aColumnas[nCol],aCol,TAB) IF aCol[2] = "T" THEN nTipo = hItemText ELSE IF aCol[3] = "1" THEN nTipo = hItemBoolean ELSE nTipo = hItemNumeric END END oItem..Name = aCol[1] oItem..Type = nTipo oItem..Size = aCol[4] HDescribeItem(oFile,oItem) nCol++ END HDescribeFile(oFile) oData is Data Source HChangeName(oData,Replace(cTableName,".","_")) HCreation(oData) StringToArray(SQLColumn("oQry"),aColumnas,CR) WHILE SQLFetch("oQry") = 0 nCol = 1 WHILE nCol <= nColumnas HToItem(oData, nCol, SQLGetCol("oQry", nCol)) nCol++ END HAdd(oData) END ELSE SQLInfo("oQry") Info("SQL error: " + SQL.MesError) END SQLDisconnect() END |

Hi
What is "very low" ?
1. YOu can create the file description in the analysis, just by conecting to your existing SQL DB
2. You can inactivate the indexes on the HF file, and reactivate them AFTER the loop, it's much faster

Hi Fabrice.
1. I don't want to describe any file in the analysis, I want to dynamically build this files and fill them with the data from the server
2. I don't know how to do this |
