DatabaseDBExistsCache Method

Determines if a particular record exists. For better performance and clarity, use this instead of DBCount(String, String, String, DataFuncOptions, String) to determine if a record or records exist. DBExistsCache is an enhancement to the existing DBExists function. Ultimately we still use the same DBExists mechanism to retrieve the required value but the result is cached to Thread Local Storage. Subsequent requests to check existence of the same value (using the SAME SQL) will pull that value from the thread cache rather than hitting the database.

public bool DBExistsCache(
	string table,
	string where,
	DataFuncOptions options = ,
	string logSource = null
)

Public Function DBExistsCache ( 
	table As String,
	where As String,
	Optional options As DataFuncOptions = ,
	Optional logSource As String = Nothing
) As Boolean
