Gets or sets an SQL statement to execute at the data source.
Assembly: System.Data.SqlServerCe (in System.Data.SqlServerCe.dll)
When the CommandType property is set to TableDirect, the property should be set to the name of the table to be accessed. TableDirect access is the fastest way to retrieve data from SQL Server Compact. You may be required to use escape character syntax if any of the tables named contain any special characters. All rows and columns of the named table or tables will be returned when you call one of the Execute methods.
The .NET Compact Framework Data Provider for SQL Server Compact supports named parameters for passing parameters to an SQL statement called by a SqlCeCommand when CommandType is set to Text. For example:
SELECT * FROM Customers WHERE CustomerID = @customerID
The Data Provider for SQL Server Compact also does not support batch queries. Commands must follow the following form: SELECT * FROM Customers and not SELECT * FROM Customers; SELECT * FROM Orders. If you are using code generated for System.Data.SqlClient, you may have to modify your queries to conform to this restriction.
Specify column names for INSERT queries when using RDA enabled replication. RDA tracked tables contain system-generated columns that will change the count of columns you may have expected for your query. If you do not specify column names and the number of columns in the INSERT statement is different from the number of columns in the table, the INSERT will fail.
