sqlstate 01000

. The basic syntax is as follows: DECLARE condition_name Condition for Condition_value Condition_value: SQLSTATE [VALUE] sqlstate_value | Mysql_error_code Where the Condition_name parameter represents the name of the condition, the Condition_value parameter represents the type of condition, and the Sqlstate_value parameter and Mysql_error_code parameter can represent the MySQL error. For example, in error 1146 (42S02), the Sqls

You can also define solutions to these problems in the handler. This method can predict possible problems in advance and propose solutions. In this way, the program's ability to handle problems can be enhanced to avoid abnormal program stop. MySQL uses the DECLARE keyword to define conditions and processing programs. This secti

declare EXIT handler is used to handle exceptions, meaning that if a 1215 error occurs, the program throws a row into the log table. Exit means to exit the compound statement when the action is successfully committed. 1. Syntax for exception handling: 1 DECLARE EXIT | CONTINUE {Error-number| {SQLSTATE error-| MySQL allows two types of processors: Exit and continue, which exits after the error-handling code is executed, and the latter can still conti

) ? 0: (H = key.hashcode ()) ^ (H >>> 16); }//The function that returns the index from the rehashed hashStatic intIndexfor (intHintlength) { returnH (length-1);}To work more efficiently, the size of the internal array must be a power value of 2. Let's take a look at why:Assuming that the length of the array is 17, the mask value is 16 (array length-1). The binary representation of 16 is 0 ... 010000, so for any value H, the result of "H 16" is 16 or 0. This means that an array of length 17
