Validating MySQL to PostgreSQL Migration

Untitled

 

Verification of the resulting database is the most significant phase of the entire migration process. The first step of the verification procedure isidentifyingthe range of objects that must be checked. Here is list of the most important database entries that have to be migrated properly:

  1. Table structures with all necessary attributes
  2. Data
  3. Indexes and foreignkeys
  4. Views

TableStructures

There are two ways to expose table definitions inMySQL:

  • run SQL query DESC table_namein MySQL command line prompt

or

  • highlight the table in the left pane and click’Structure’ link in phpMyAdmin

PostgreSQL allows to browse table definitionsvia \d table_name query.

Table definition is considered as properly converted when every column in resulting PostgreSQL table has the same type, size and default value as in the original MySQLtable.

The Data

Conversion of thedata is validatedby comparison of random fragmentsof source MySQL and destination PostgreSQL tables. MySQL allows to extractfragments of data as follows:

  • run SQL query: SELECT * FROM table_name LIMIT start_record, number_of_recordsin MySQL command line prompt

or

  • highlight the table in the left pane and select ‘Browse’ tab in phpMyAdmin

PostgreSQL also provides SELECT-query to extract the fragment of data. It has similar syntaxwith MySQL one specified above:

SELECT * FROM table_name LIMIT number_of_records OFFSET start_record

Besides data comparison, it is also importantto check that source and destination tables have equalnumber of rows. Both MySQL and PostgreSQL allow to get number of rows using thequery:

SELECT COUNT(*) FROM table_name

The Indexes

There are two ways to get information about indexes in MySQL:

  • run SQL query SHOW INDEXES FROM table_namein MySQL console

or

  • highlight the corresponding table in left pane of phpMyAdmin, click ‘Structure’ link and allindexes will appear right after the table definition

PostgreSQL listsindexes at the bottom of table DDL generated through the following statement: \d table_name

The Foreign Keys

MySQL offers two options to expose information about foreign keys:

  • run SQL-query: SHOW CREATE TABLE `table name`from MySQL command prompt

or

  • highlight the corresponding table in left pane of phpMyAdmin,select ‘Structure’ and click the ‘Relations view’ linkbelow table definition

PostgreSQL stores information about foreign keys inthe service table “information_schema”. It can be extracted via the following query:

SELECTtc.constraint_name, tc.table_name, kcu.column_name, ccu.table_name AS fk_table_name,ccu.column_name AS fk_column_nameFROM information_schema.table_constraints AS tc    JOIN information_schema.key_column_usage AS kcu      ON tc.constraint_name = kcu.constraint_name    JOIN information_schema.constraint_column_usage AS ccu      ON ccu.constraint_name = tc.constraint_nameWHERE constraint_type = ‘FOREIGN KEY’ AND tc.table_name=’table_name’;

The Views

Theonlyway to validate conversion of viewsis to compare SELECT-statements of every view in source MySQL and destination PostgreSQL databases with respect to differences between SQL dialects of these two DBMS. Thistaskrequires extensive skills of database programming.

At the sametime, the views from source and the destination databases can be easily listed.MySQL lists all views through the following query:

SHOW FULL TABLES IN db_name WHERE TABLE_TYPE LIKE ‘VIEW’;

PostgreSQL allows to list all views in the database using this query:

SELECT table_name FROM INFORMATION_SCHEMA.views; More articles about PostgreSQL can be found here: https://www.convert-in.com/docs/sql2pgs/contents.htm

A best audio interface is required to produce music

a

However, the bass is less noticeable because they don’t move as much air. Headphones will only need to send the sound waves a few millimetres so your eardrums Therefore the headphone components are much smaller and often more precise than the speaker components. Modern-day headphones can be both wired or wireless. The output is much lower when compared to the standalone speakers; the close proximity of headphones to your ears can make the volume sound very loud. You should pick out the audio interface from the best audio interfaces of 2018.

Standalone speakers:

The digital headphones will also include a digital-to-analog converter, or DAC, to produce the analogue output. The headphones function in the same way like the standalone speakers but the output is significantly different. The speakers must generate enough amplitude for the sound to be audible from a far distance. The biggest difference between loudspeakers and headphones is only the size. A loudspeaker needs to set all the air moving in a room so that you can hear the sound it is making. But the speaker in a headphone will only move the volume of air inside your ear canal.

Few common mistakes people make while hiring one of the search engine optimization companies in Australia

casino

Hiring an SEO company who could manage all your company’s marketing services online is one of the major tasks that need to be accomplished these days. Most of the times we are tasked with hiring such an SEO company that can be considered one of the best search engine optimization companies in Australia. Choosing such an SEO company for the betterment of your business can be done in many ways but they can be categorized into two, the right way and the wrong way. The wrong way is characterized by a few common pitfalls that are best avoided. These pitfalls are also commonly frequented by many companies who are in search of one of the search engine optimization companies in Australia.

  1. Never filter your choice using Google

Google provides the best answer to most of our questions but when searching for one of the best search optimization companies in Australia a Google search won’t really help you. It will misguide you. If you think simplistically then you might have the notion that a good SEO company will have a good ranking in Google. But that notion will seldom hold true. Good SEO companies perform very well and they get their well-deserved referrals. Rankings do not really matter to them. They are always preoccupied with a huge number of clients as they keep on referring these companies to their folks and so on. They retain most of their clients and hence are kept always busy. This makes them the least amount of time and money on optimizing their own company in order to secure more clients.

  1. Never believe in a secret sauce

Many SEO companies use a common sales pitch which is they have a secret sauce. Sadly, all such SEO companies are low-quality. There is no such thing as a secret sauce in the world of SEO. You never hear one of the best SEO companies in Australia mention such a term as the secret sauce. Any SEO company saying that they have a secret weapon or methodology that will work wonders for your website but they cannot really expose that plan to you because well, it’s a secret, should be thoroughly rejected. There is no such process because SEO is actually an open field of work which everybody associated with understands well. It originated among much secrecy but has since then evolved a lot to not remain a secret anymore. Such an answer with a mention of a secret5 sauce must be considered as a red flag.

  1. Never trust a list having top SEO names

Ever come across websites such as top10SEO.com or bestSEOs.com while searching for one of the best Search engine optimization companies in Australia? They are nothing but plain aggregators. They rank out the companies with terms like “best SEO” and “top SEO” and then they make a list of these companies and sell them to you. Never believe in such lists.

Securing one of the best search engine optimization companies in Australia is currently one of the required tasks for any company. Remember not to commit any of the above mistakes while doing so.
