    public function index()
    {
        //设置过滤方法
        $this->request->filter(['strip_tags', 'trim']);
        if (false === $this->request->isAjax()) {
            return $this->view->fetch();
        }
        //如果发送的来源是 Selectpage，则转发到 Selectpage
        if ($this->request->request('keyField')) {
            return $this->selectpage();
        }
        [$where, $sort, $order, $offset, $limit] = $this->buildparams();

        $list = \think\Db::connect("db_config.dbconfigname", 'dbname')
            ->table('fa_uran_companyinfo')
            ->where($where)
            ->order($sort, $order)
            ->paginate($limit);
        $result = ['total' => $list->total(), 'rows' => $list->items()];
        return json($result);
    }

 

基于宝塔

软件商店中 安装 PostgreSQL管理器 

然后安装最新版 pgsql 16

然后在要连接的pgsql数据库中执行thinkphp\library\think\db\connector\pgsql.sql

如果是pgsql16版本,即版本号大于12，则需要修改为以下脚本

CREATE OR REPLACE FUNCTION pgsql_type(a_type varchar) RETURNS varchar AS
$BODY$
DECLARE
     v_type varchar;
BEGIN
     IF a_type='int8' THEN
          v_type:='bigint';
     ELSIF a_type='int4' THEN
          v_type:='integer';
     ELSIF a_type='int2' THEN
          v_type:='smallint';
     ELSIF a_type='bpchar' THEN
          v_type:='char';
     ELSE
          v_type:=a_type;
     END IF;
     RETURN v_type;
END;
$BODY$
LANGUAGE PLPGSQL;

CREATE TYPE "public"."tablestruct" AS (
  "fields_key_name" varchar(100),
  "fields_name" VARCHAR(200),
  "fields_type" VARCHAR(20),
  "fields_length" BIGINT,
  "fields_not_null" VARCHAR(10),
  "fields_default" VARCHAR(500),
  "fields_comment" VARCHAR(1000)
);

CREATE OR REPLACE FUNCTION "public"."table_msg" (a_schema_name varchar, a_table_name varchar) RETURNS SETOF "public"."tablestruct" AS
$body$
DECLARE
    v_ret tablestruct;
    v_oid oid;
    v_sql varchar;
    v_rec RECORD;
    v_key varchar;
BEGIN
    SELECT
        pg_class.oid  INTO v_oid
    FROM
        pg_class
            INNER JOIN pg_namespace ON (pg_class.relnamespace = pg_namespace.oid AND lower(pg_namespace.nspname) = a_schema_name)
    WHERE
            pg_class.relname=a_table_name;
    IF NOT FOUND THEN
        RETURN;
    END IF;

    v_sql='
     SELECT
           pg_attribute.attname AS fields_name,
           pg_attribute.attnum AS fields_index,
           pgsql_type(pg_type.typname::varchar) AS fields_type,
           pg_attribute.atttypmod-4 as fields_length,
           CASE WHEN pg_attribute.attnotnull  THEN ''not null''
           ELSE ''''
           END AS fields_not_null,
           pg_get_expr(pg_attrdef.adbin, pg_attribute.attrelid) AS fields_default,
           pg_description.description AS fields_comment
     FROM
           pg_attribute
           INNER JOIN pg_class  ON pg_attribute.attrelid = pg_class.oid
           INNER JOIN pg_type   ON pg_attribute.atttypid = pg_type.oid
           LEFT OUTER JOIN pg_attrdef ON pg_attrdef.adrelid = pg_class.oid AND pg_attrdef.adnum = pg_attribute.attnum
           LEFT OUTER JOIN pg_description ON pg_description.objoid = pg_class.oid AND pg_description.objsubid = pg_attribute.attnum
     WHERE
           pg_attribute.attnum > 0
           AND attisdropped <> ''t''
           AND pg_class.oid = ' || v_oid || '
     ORDER BY pg_attribute.attnum' ;

    FOR v_rec IN EXECUTE v_sql LOOP
            v_ret.fields_name=v_rec.fields_name;
            v_ret.fields_type=v_rec.fields_type;
            IF v_rec.fields_length > 0 THEN
                v_ret.fields_length:=v_rec.fields_length;
            ELSE
                v_ret.fields_length:=NULL;
            END IF;
            v_ret.fields_not_null=v_rec.fields_not_null;
            v_ret.fields_default=v_rec.fields_default;
            v_ret.fields_comment=v_rec.fields_comment;
            SELECT constraint_name INTO v_key FROM information_schema.key_column_usage WHERE table_schema=a_schema_name AND table_name=a_table_name AND column_name=v_rec.fields_name;
            IF FOUND THEN
                v_ret.fields_key_name=v_key;
            ELSE
                v_ret.fields_key_name='';
            END IF;
            RETURN NEXT v_ret;
        END LOOP;
    RETURN ;
END;
$body$
    LANGUAGE 'plpgsql' VOLATILE CALLED ON NULL INPUT SECURITY INVOKER;

COMMENT ON FUNCTION "public"."table_msg"(a_schema_name varchar, a_table_name varchar)
    IS '获得表信息';

---重载一个函数
CREATE OR REPLACE FUNCTION "public"."table_msg" (a_table_name varchar) RETURNS SETOF "public"."tablestruct" AS
$body$
DECLARE
    v_ret tablestruct;
BEGIN
    FOR v_ret IN SELECT * FROM table_msg('public',a_table_name) LOOP
            RETURN NEXT v_ret;
        END LOOP;
    RETURN;
END;
$body$
    LANGUAGE 'plpgsql' VOLATILE CALLED ON NULL INPUT SECURITY INVOKER;

COMMENT ON FUNCTION "public"."table_msg"(a_table_name varchar)
    IS '获得表信息';

 

然后在多数据库配置文件db_config.php中，手动添加pgsql的连接

,
  'pgsqlmac' =>
    array(
      'type' => 'pgsql',
      'hostname' => '127.0.0.1',
      'hostport' => '3456',
      'database' => 'dbname',
      'username' => 'username',
      'password' => 'pwd',
    ),

 

在php控制器中这样调用

  $list = \think\Db::connect("db_config.pgsqlmac", 'public.dbname')
            ->table('fa_com_tablename')
            ->where($where)
            ->order($sort, $order)
            ->paginate($limit);
