mysql - 使用外键创建表 - 错误 150

Question

实际上，我使用这个sql脚本在mysql 5.0.24上创建表方案，它工作正常，问题是当我在mysql 5.5.16上尝试相同的脚本时，我收到以下错误消息:

general error message from server: "can't create table 'amdb.am_wta_methodtree' (errno: 150)"

这是我的 sql:

create table AM_WTA_MethodInstance(
"ID" BIGINT NOT NULL,
"TRANSACTIONID" BIGINT NOT NULL,
"INVOCATIONTIME" BIGINT NOT NULL,
"METHODIDENTIFIERID" BIGINT NOT NULL,
"THREADID" VARCHAR(255) NOT NULL,
"INCLUSIVETIME" BIGINT NOT NULL DEFAULT 0,
"EXCLUSIVETIME" BIGINT NOT NULL DEFAULT 0,
"STATUS" INTEGER(1) NOT NULL DEFAULT 0,
"EXCEPTIONMESSAGE" TEXT,
PRIMARY KEY ("ID"),
FOREIGN KEY(METHODIDENTIFIERID) REFERENCES AM_WTA_MethodIdentifier(ID),
FOREIGN KEY(TRANSACTIONID) REFERENCES AM_WTA_Transaction(TRANSACTIONID) ON DELETE CASCADE)

create table AM_WTA_MethodTree(
"PARENTID" BIGINT NOT NULL,
"CHILDID" BIGINT NOT NULL,
"INVOCATIONTIME" BIGINT NOT NULL,
PRIMARY KEY ("PARENTID","CHILDID"),
FOREIGN KEY(PARENTID,CHILDID) REFERENCES AM_WTA_MethodInstance(ID,ID) ON DELETE CASCADE)

Answer 1

如果您创建表提交并在创建外键后它应该可以工作。

谢谢
