%SQL.ExImData

abstract class %SQL.ExImData

Common data used by both SQL import and export classes.

Example of using the import/export classes:

	If Wizard = "Export" { set mgr = ##class(%SQL.Export.Mgr).%New() }
	Else { Set mgr = ##class(%SQL.Import.Mgr).%New() }
	Set mobj = ##class(%SQL.Manager.API).%New()
	Set ok = mobj.CheckIdentifier(.SchemaName)
	Set ok = mobj.CheckIdentifier(.TableName)
	Set classname = mobj.FindClassName(SchemaName_"."_TableName)
	Set mgr.FileName = "c:\export.txt"
	Set mgr.TableName = SchemaName_"."_TableName
	Set mgr.IQN=$$$BuildIQN(SchemaName,TableName)	<-- $$$BuildIQN is defined in %msql.INC
	Set mgr.ClassName = classname
	Set mgr.Delimiter = $c(9)			<-- tab
	Set mgr.StringQuote = ""			<-- double quotes
	Set mgr.DateFormat = 1				<-- MM/DD/{YY}YY
	Set mgr.TimeFormat = 1				<-- hh:mm:ss
	Set mgr.TimeStampFormat = 1			<-- ODBC format (Import only)
	Set mgr.NoCheck = 1				<-- disable validation (Import only)
	Set mgr.HasHeaders = 1				<-- import file contains column headers
	Do mgr.ColumnNames.Insert(colname)		<-- insert a column name
	Do mgr.ColumnTypes.Insert(datatype)		<-- insert a column datatype

For Export:
	Set result = mgr.GenerateExportRoutine()
	If result '= 1 { Write !,"Error generating export routine: ",result Quit }
	Set sta = mgr.OpenExport()
	If $$$ISERR(sta) {
		Set ErrMsg = "Unable to open export file"
		[...LogYourError here ]
	} Else {
		Set sta = mgr.GetExportSize(.size)
		If size = 0 {
			[...LogYourError here "No data to export"]
		} Else {
			Set tSC = $$$OK
			Do {
				Set tSC = mgr.ExportRows(.rows,.done)
				Set total = total + rows
				If $$$ISERR(tSC) [Do ..LogYourError here] Quit
			} While done = 0
			If $$$ISOK(tSC) {
				Set tmsg = "Completed at "_$zdt($h)
			} Else {
				Set tmsg ="Error occurred during export."
			}
			Set statusmsg = "Exported: "_total_" rows"
			Write !,tmsg,!,statusmsg
		}
		Do mgr.CloseExport()
	}
	Do mgr.DeleteExportRoutine()

For Import:
	Set mgr.DeferIndices = 1
	Set result = mgr.GenerateImportRoutine()
	If result '= 1 { Write !,"Error generating import routine: ",result Quit }
	Set sta = mgr.OpenImport()
	If $$$ISERR(sta) {
		Set ErrMsg = "Unable to open import file"
		[...LogYourError here ]
	} Else {
		If mgr.HasHeaders = 1 { Set sta = mgr.ReadHeader(.header,.size) }
		Set tSC = $$$OK
		Do {
			Set tSC = mgr.ImportRows(.rows,.inserted,.bytes,.done,.numerr,total)
			Set total = total + rows
			Set totalinserted = totalinserted + inserted
			Set totalbytes = totalbytes + bytes
			If $$$ISERR(tSC) [...LogYourError here ] Quit
		} While done = 0
		Do mgr.BuildIndices()
		If mgr.ErrorCount() > 0 {
			[...LogYourError here ]
			[number of error count is mgr.ErrorCount()
		} Else {
			If $$$ISOK(tSC) {
				Set tmsg = "Completed at "_$zdt($h)
			} Else {
				Set tmsg ="Error occurred during import."
			}
			Set statusmsg = "Imported: "_totalinserted_" rows"
			Write !,tmsg,!,statusmsg
		}
		Do mgr.CloseImport(0)
	}
	Do mgr.DeleteImportRoutine()
