%SYS.PTools.SQLQuery

persistent class %SYS.PTools.SQLQuery extends %Library.Persistent

SQL Table Name: %SYS_PTools.SQLQuery

This is the parent class of %SYS_PTools.SQLStats.

This class stores the general info of a query from compile time: QueryText, QueryType, CursorName, RoutineName, and NameSpace. All of the run time data is stored in the %SYS_PTools.SQLStats class.

Error information is stored in ^%sqlcq(NAMESPACE,"PTools","Error",$J).

Methods

classmethod Export(FileName="", delim="", ExportPlan=0) as %String

##class(%SYS.PTools.SQLQuery).Export(FileName,delim,ExportPlan)

FileName
Path and name of the file you want to export to.
delim
Default value $c(9) (tab) Delimiter for the columns of the export file.
ExportPlan
Optional. Default value = 0 if 1 then the SQL Show Plan will be included as part of the export
This method is used to export data from the %SYS.PTools.SQLQuery class to a delimited text file.
classmethod LogHeader(File, version, delim)
classmethod NewQuery(ByRef SQLText As %String, SQLType As %String, NameSpace As %String, RoutineName As %String, CursorName As %String, CompileTime As %Numeric = 0) as %Status
This method is called at compile time for a query It deletes all current stats for this query, as they could be very different after the compile
