PostgreSql数据库中布尔类型的用法

1、启动navicat查询窗口，输入如下建表语句CREATE TABLE "public"."bool_type_test" ( "bool_field" bool);

2、输入如下语句，插入布尔值为真的记录INSERT INTO "public"."bool_type_test"("bool_field") VALUES ('t');INSERT INTO "public"."bool_type_test"("bool_field") VALUES ('true');INSERT INTO "public"."bool_type_test"("bool_field") VALUES ('yes');INSERT INTO "public"."bool_type_test"("bool_field") VALUES (TRUE);INSERT INTO "public"."bool_type_test"("bool_field") VALUES ('1');

3、输入如下语句，插入布尔值为假的记录INSERT INTO "public"."bool_type_test"("bool_field") VALUES ('f');INSERT INTO "public"."bool_type_test"("bool_field") VALUES ('false');INSERT INTO "public"."bool_type_test"("bool_field") VALUES ('no');INSERT INTO "public"."bool_type_test"("bool_field") VALUES (FALSE);INSERT INTO "public"."bool_type_test"("bool_field") VALUES ('0');

4、输入如下语句，可以查询数据库中存储的记录select * from bool_type_test
