我有一個int
變量包含值例如。 31012015
但我試圖將日期格式eg
轉換爲dd-mm-yyyy
。我查詢的部分是:如何將整數轉換爲日期Postgres dblink
select * from dblink(
'dbname=dbexample port=5432 host=127.0.0.1 user=postgres password=root',
'select * from tableexample where fconclusion between 2014-01-02 and 2014-12-31')
as k(
id_principal integer,
nestrategia smallint,
ctitulo character varying(300),
factivacion date,
nestado smallint,
fcreacion timestamp without time zone,
id_usuario integer,
nstatus smallint,
nmunicipio smallint,
nactividad smallint,
fconclusion date,
id_personal integer,
nactivo smallint,
fmodificacion date,
nconclusion smallint
)
PgAdmin
顯示下一個錯誤:
ERROR: operator does not exist: date> = integer HINT: No operator matches the name and type of arguments. You may need to add explicit type conversions. CONTEXT: Error Occurred on dblink connection named "unnamed": could not execute query.
有人能幫助我嗎?
