Re: Synchronizing a table that is two different databases : Need to dump a table a insert from db1 and change the insert statements into UPDATE statements

In theory, you could write a script that opens both DBs, then systematically inserts or updates records in the destination DB table based on what's in the source DB table. Brute force, but automatable.

Subject: [GENERAL] Synchronizing a table that is two different databases : Need to dump a table a insert from db1 and change the insert statements into UPDATE statements

Hi all

Synchronizing a table that is in two different databases(e.g db1 and db2).

Please help me with this. I need to dump a table as INSERTS from db1 (postgres 9.1.2) and change the INSERT statements into UPDATE statements in order to apply that change in db2(postgres 8.3.0.112) which has the same table as db1. Where the record does not exist I need to insert that record. There is more than 1000 INSERTS I need to convert to UPDATES for the same table. Please help .

Example:

Below it's the INSERT from postgres 9.1.2 DATABASE which should convert to UPDATE statement.

INSERT INTO table (br_cde, br_desc, br_active, br_closed, grp_cde, ctry_cde, state_cde, br_addr_line1, br_addr_line2, br_addr_line3, br_addr_line4, br_addr_cde, br_post_addr_line1, br_post_addr_line2, br_post_addr_line3, br_post_addr_line4, br_post_addr_cde, br_phone, tax_cde, br_server_name, br_lang_ind, bureau_cde, br_risk_typ_cde, br_access_ccd, br_access_bureau, br_network_active, br_desc_short, br_is_trading, br_is_test, br_is_nomodem, br_is_whs, br_is_merch, br_is_cco, br_is_central, br_is_merch_active, br_central_brn, br_merch_brn, br_cco_brn, br_cgo_brn, br_cluster_brn, br_contact, br_tollfree, br_fax, br_telex, br_email, ops_cde, ops_director, br_cmpy_reg, br_tax_reg, audit_id, comp_cde, br_batch, br_release_pilot_type, br_is_order_active, bnk_id, br_class_cde, br_erp_xref, br_to_open, br_to_close, br_comments, br_is_hire, br_is_voucher, br_is_clear_center, br_is_headoffice, br_is_nsp_active, usr_pass_history, br_network_protocol, br_gen_ins_central_brn, br_cpi_ins_central_brn, br_rsc_area, br_rsc_perc, br_switch_deduc, br_tvlic_dealer_no, br_cco_followup, br_triad_live, br_do_cust_locking, br_is_rainbow, br_nca_live, br_ncr_reg_no, prov_cde, br_is_data_archive, br_icu_brn, br_living_expenses_live, br_ab_dorder_live, br_ab_receipts_active, br_spiv_max_alloc_perc, br_merger_brn, br_dep_bnk_acc, br_merchant_number, br_goods_ins_live, br_cgs_connection, whs_cde, br_crm_brn, subscription_active, br_prn_doc_default_active, br_use_jms, br_sso_active, br_paym8_properties, creditors_supp_no_prefix, br_block_debtors_obo, ccms_branch, br_is_ccms_live, ceres_conv_flag, cims_branch, br_is_cims_live, br_accept_sql_releases) VALUES ('9940', 'ELLERINES CENTRAL - 9940', true, NULL, '1', 'BAF', 'BAF', '209 SMIT STREET', 'BRA', 'Jgf', 'Jrg', '3025', '209 SMIT STREET', 'BRA', 'Jrg', NULL, '2017', '(4562) 712 1300', '1', 'dfgike.com<http://dfgike.com>', 'ENG', 'ITC', 'L', false, false, false, 'BATCH - 9940', false, false, false, false, false, false, true, false, '9940', NULL, NULL, '10.52.1.31', '9940', 'DOUG', NULL, '(4562) 712 1300' ', NULL, NULL, '001', NULL, '1969/02687/07', NULL, 0, NULL, '9940', NULL, false, NULL, NULL, NULL, NULL, NULL, NULL, false, false, false, false, false, 30, 'WS2~WS2', '1002', '1002', NULL, NULL, false, NULL, NULL, false, true, false, true, 'NC', NULL, true, NULL, true, true, NULL, NULL, NULL, NULL, NULL, true, 'oracle_live', NULL, NULL, true, NULL, true, false, NULL, NULL, NULL, NULL, NULL, NULL, NULL, false, false);
