修改字段


BEGIN TRANSACTION;


ALTER TABLE "proxyip" RENAME TO sqlitemanager_temp_table_14678003456;


CREATE TABLE "proxyip" ("column1" INTEGER PRIMARY KEY AUTOINCREMENT,"column23" TEXT);


INSERT INTO "proxyip" ("column1","column23") SELECT "column1","column24" FROM sqlitemanager_temp_table_14678003456;


DROP TABLE sqlitemanager_temp_table_14678003456;


COMMIT;

删除字段


BEGIN TRANSACTION;


ALTER TABLE "proxyip" RENAME TO sqlitemanager_temp_table_14465963723;


CREATE TABLE "proxyip" ("column1" INTEGER PRIMARY KEY AUTOINCREMENT);

INSERT INTO "proxyip" ("column1") SELECT "column1" FROM sqlitemanager_temp_table_14465963723;


DROP TABLE sqlitemanager_temp_table_14465963723;
