problems while executing a sql command in vb
I have a problem with a sql query. Through the query I am trying to search data开发者_如何学运维base for any occurrences of string (can be anything) in a column using the SQL LIKE command. The problem is that it works fine for most of the strings say john, jim, ji"m , but does not work when i include the following characters which are ( ' , { , } , and a single quotation mark). MYSQL query takes care of these special cases by putting them in [] block whenever user enters them .
But i am getting the following error when i go to query the database using the GetSelectCommand() in VB.NET
Exception Details:
System.ApplicationException: Number of values provided must be equal to the number of placeholders in query.
I have checked the query over and over again .. but its fine .
My database server is Sql Server 2008.
So my application throws the exception in this command:
Using reader As MustDisposeDataReader = _
pmSystem.DatabaseManager.GetSelectCommand(selectStatementBuilder.ToString(), New Object() {})
Where MustDisposeDataReader
is an instance of a class in an internally developed library, which inherits from System.Object
. pmSystem
is an instance of the class PlanManagerSystem
which implements the commandlayer. GetSelectCommand()
takes the select command
Your single quotes are probably formatted incorrectly. Since it says the number of values are wrong it looks like your single quotes are off.
