Question

我有以下查询来创建表：

  CREATE TABLE qrtz_simprop_triggers
            (          
            SCHED_NAME VARCHAR(120) NOT NULL,
            TRIGGER_NAME VARCHAR(200) NOT NULL,
            TRIGGER_GROUP VARCHAR(200) NOT NULL,
            STR_PROP_1 VARCHAR(512) NULL,
            STR_PROP_2 VARCHAR(512) NULL,
            STR_PROP_3 VARCHAR(512) NULL,
            INT_PROP_1 INT NULL,
            INT_PROP_2 INT NULL,
            LONG_PROP_1 BIGINT NULL,
            LONG_PROP_2 BIGINT NULL,
            DEC_PROP_1 NUMERIC(13,4) NULL,
            DEC_PROP_2 NUMERIC(13,4) NULL,
            BOOL_PROP_1 BOOL NULL,
            BOOL_PROP_2 BOOL NULL,
            PRIMARY KEY (SCHED_NAME,TRIGGER_NAME,TRIGGER_GROUP)) ENGINE=InnoDB 
default charset=<value of character_set_client>;

也就是说，如果character_set_client的值为UTF8，则默认字符集应为utf8；如果character_set_client为latin1，则默认字符集应为是latin1。

这对我来说非常重要，即使花费数小时我也无法破解。任何帮助将不胜感激。

You'd have to do this with dynamic SQL. You can't use variables directly in a CREATE TABLE statement.

SET @sql = CONCAT('CREATE TABLE ... DEFAULT CHARSET=', @@character_set_client);
PREPARE stmt FROM @sql;
EXECUTE stmt;
DEALLOCATE PREPARE stmt;

However, I wonder why you're doing this. I would normally allow the table charset to default to the charset for the schema. It seems odd to use the client charset.

在MySQL中将character_set_client指定为Table的默认字符集
