NAME
dblink_build_sql_insert - builds an INSERT statement using a local tuple, replacing the primary key field
values with alternative supplied values
SYNOPSIS
dblink_build_sql_insert(text relname,
int2vector primary_key_attnums,
integer num_primary_key_atts,
text[] src_pk_att_vals_array,
text[] tgt_pk_att_vals_array) returns text
DESCRIPTION
Note
The following description applies only to Postgres-XC
dblink module has not been tested with Postges-XC yet. Although there're no reason that dblink does not
run in Postgres-XC, the development team leaves the test and the use of this module entirely to users.
This section is identical to the corresponding PostgreSQL reference manual.
Note
The following description applies only to PostgreSQL
dblink_build_sql_insert can be useful in doing selective replication of a local table to a remote
database. It selects a row from the local table based on primary key, and then builds a SQL INSERT
command that will duplicate that row, but with the primary key values replaced by the values in the last
argument. (To make an exact copy of the row, just specify the same values for the last two arguments.)

Note
The following description applies only to PostgreSQL
relname
Name of a local relation, for example foo or myschema.mytab. Include double quotes if the name is
mixed-case or contains special characters, for example "FooBar"; without quotes, the string will be
folded to lower case.
primary_key_attnums
Attribute numbers (1-based) of the primary key fields, for example 1 2.
num_primary_key_atts
The number of primary key fields.
src_pk_att_vals_array
Values of the primary key fields to be used to look up the local tuple. Each field is represented in
text form. An error is thrown if there is no local row with these primary key values.
tgt_pk_att_vals_array
Values of the primary key fields to be placed in the resulting INSERT command. Each field is
represented in text form.
RETURN VALUE

Note
The following description applies only to PostgreSQL
As of PostgreSQL 9.0, the attribute numbers in primary_key_attnums are interpreted as logical column
numbers, corresponding to the column's position in SELECT * FROM relname. Previous versions interpreted
the numbers as physical column positions. There is a difference if any column(s) to the left of the
indicated column have been dropped during the lifetime of the table.
