Methods

  Name Description
Protected method AddStatement(String) Add a statement to the current SQL batch. You must call PrepareSqlBatch before you call AddStatement.
Protected method AddStatement(String, Int32) Add a statement to the current SQL batch. You must call PrepareSqlBatch before you call AddStatement. If the number of parameters that will be added by using this statement will exceed the maximum number of allowed parameters in a single SQL batch, the statements that are already part of the batch will be executed, and then a new batch will begin with the statement that's being added.
Protected method AddStatement(String, Int32, Boolean) Add a statement to the current SQL batch. You must call PrepareSqlBatch before you call AddStatement. If the number of parameters that will be added by using this statement will exceed the maximum number of allowed parameters in a single SQL batch, the statements that are already part of the batch will be executed, and then a new batch will begin with the statement that's being added.
Protected method AddStatement(String, Int32, Boolean, Boolean) Add a statement to the current SQL batch. You must call PrepareSqlBatch before you call AddStatement. If the number of parameters that will be added by using this statement will exceed the maximum number of allowed parameters in a single SQL batch, the statements that are already part of the batch will be executed, and then a new batch will begin with the statement that's being added.

Protected method TraceLeave Trace exit from a method with a consistently formatted message and a time stamp.
Protected method TranslateException Examines a SQL Type Exception and transforms it into a more significant one.The default behavior is to do nothing; that is, it is to rethrow the original exception.WIT is the only component that currently overrides the current behavior.
Public methodStatic member TranslateSqlException Not all TFS services use TeamFoundationSqlResourceComponent, but most want to use the common error handling that it contains. Therefore, a static TranslateSqlException can be used externally from the component.
