1.原SQL

CREATE FUNCTION wmspci_app.pro_p1()
    RETURNS record
    LANGUAGE 'plpgsql'
    
AS $BODY$
declare
  v_rec          record; 
  _c varchar;
  v_sysdate      timestamp;
  v_cnt          numeric(6);
  sfc            record;   
  v_sap_fact_no    sap_dispatchingm_bak.ffact_no%type;
  v_ffact_no       dispatchingm_bak.ffact_no%type;

begin
    raise notice 'now is %', clock_timestamp();
END;
$BODY$;

2.錯誤

输出错误如下：

ERROR: invalid type name "sap_dispatchingm.ffact_no%type"
LINE 18: v_sap_fact_no sap_dispatchingm.ffact_no%type;

3.解决方法

指定table所在的schema name

CREATE FUNCTION wmspci_app.pro_p1()
    RETURNS record
    LANGUAGE 'plpgsql'
    
AS $BODY$
declare
  v_rec          record; 
  _c varchar;
  v_sysdate      timestamp;
  v_cnt          numeric(6);
  sfc            record;   
  v_sap_fact_no    wmspci_app.sap_dispatchingm_bak.ffact_no%type;
  v_ffact_no       wmspci_app.dispatchingm_bak.ffact_no%type;

begin
    raise notice 'now is %', clock_timestamp();
END;
$BODY$;```
结果如下：

```bash
CREATE FUNCTION
