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

       Returns the requested SQL statement as text.

           Note

           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.
