sql - 函数中命名参数的 PostgreSQL 问题

Question

Linux 上的 PostgreSQL 8.4。我有一个功能:

CREATE OR REPLACE FUNCTION production.add_customer (  
name varchar(100),  
email_address varchar(300),  
street_address text,  
city varchar(50),  
state varchar(2),  
zip varchar(10),  
secret1 bytea,  
secret2 bytea,   
secret3 bytea,  
secret4 bytea,  
referrer text)  
RETURNS integer as $$  
BEGIN  
INSERT INTO customers (name, email_address, street_address, city, state, zip, secret1, secret2, secret3, secret4, create_date, referrer) VALUES  
(name, email_address, street_address, city, state, zip, create_date, referrer
pgp_sym_encrypt(secret1, 'reallylongrandomstring'),   
pgp_sym_encrypt(secret2, 'reallylongrandomstring'),   
pgp_sym_encrypt(secret3, 'reallylongrandomstring'),   
pgp_sym_encrypt(secret4, 'reallylongrandomstring'),   
current_timestamp, referrer);  
RETURNING customer_id;  
END;  
$$ LANGUAGE plpgsql;   

当我尝试创建它时返回此错误:

ERROR:  syntax error at or near "$1"
LINE 1: INSERT INTO customers ( $1 ,  $2 ,  $3 ,  $4 ,  $5 ,  $6 ,  ...
                            ^
QUERY:  INSERT INTO customers ( $1 ,  $2 ,  $3 ,  $4 ,  $5 ,  $6 ,  $7 ,  $8 ,  $9 ,  $10 , create_date,  $11 ) VALUES ( $1 ,  $2 ,  $3 ,  $4 ,  $5 ,  $6 , create_date,  $11  pgp_sym_encrypt( $7 , 'reallylongrandomstring'), pgp_sym_encrypt( $8 , 'reallylongrandomstring'), pgp_sym_encrypt( $9 , 'reallylongrandomstring'), pgp_sym_encrypt( $10 , 'reallylongrandomstring'), current_timestamp,  $11 )
CONTEXT:  SQL statement in PL/PgSQL function "add_customer" near line 8
myserver=#

我已经尝试过 ALIAS FOR，但没有成功。想法？

Answer 1

您的参数与 INSERT 中的列同名； PL/pgSQL 错误地用参数替换了两个 标识符集(列和值)，以您在错误中看到的无意义的INSERT 结束。

请参阅 this page 上的注意部分对于官方说法 - 但本质上您需要更改参数名称。
