Example of a MySQL stored procedure with parameters: Http://wwty.iteye.com/blog/698239 The mysql Stored Procedure also provides the exception handling function: the implementation of exception declaration is completed by defining HANDLER. Syntax: DECLARE handler_type handler for condition_value [,...] sp_statement handler_type: CONTINUE | EXIT condition_value: SQLSTATE [VALUE] sqlstate_value | condition_name | SQLWARNING | not found | SQLEXCEPTION

MySQL stored procedures also provide functionality for exception handling: the implementation of exception declarations is accomplished by defining handlerThe syntax is as follows:DECLARE Handler_type handler for condition_value[,...] Sp_statement handler_type:continue | EXIT condition_value:sqlstate [value] sqlstate_value | Condition_name | sqlwarning | Not FOUND | SQLEXCEPTION | Mysql_error_codeHandlers Type:1, exit: Exits the current code block (possibly a child code block or a main code bloc

In MySQL, specific exceptions require specific processing. These exceptions can be linked to errors, as well as general process control in subroutines. Defining an exception is a prior definition of the problem encountered during the execution of a program, which defines how it should be handled when a problem is encountered, and that the stored procedure or function can continue to execute when an error is encountered or a warning. 1 Exception definition 1.1 Grammar DECLARE condition_name co

The standard SQLException provides a standardized information segment (SQLState) and a vendor-specific information segment (ErrorCode). As with most databases and their JDBC driver implementations, Oracle databases and JDBC drivers provide more detailed information about the problem through vendor-specific error codes than through SQLException vendor-Independent SQLState The component provides much more inf

In MySQL, specific exceptions require specific processing. These exceptions can be linked to errors, as well as general process control in subroutines.

Stored Procedure 5-handling of conditions and exceptions and handling of Stored Procedure exceptions Exception Handling can be used for general process control in subprograms. If you want to handle errors during SQL Execution, you can use exception handling. For example, for errors or warnings that may occur in Stored Procedures, triggers, or internal functions, capture related exceptions or exceptions, and then handle them accordingly. I.

Introduction: DB2Conditional processors play an irreplaceable role in stored procedures. In DB2,SQLThe stored procedure can use the DB2 Condition processor (Condition Handler) to processSQL Error(SQLERROR), SQL warning (SQLWARNING), no data (NOT FOUND) three common conditions and your own defined trigger conditions, you can use include EXIT, CONTINUE) three condition processors, including UNDO and UNDO. The following describes the detailed analysis of SQL errors processed by the DB2 conditional

handle exceptions or directly return them to the caller. Here, condition is translated as an exception for readers to understand. In fact, some exceptions (condition) are not caused by errors, which will be described in detail below. When the sqlstate returned by the statement in the Stored Procedure exceeds 00000, it indicates that an exception (condition) is generated in the stored procedure ), it indicates that an error occurs, data is not found
