While SQL sets the standard for string literals being used in single quotes and identifiers being used in double quotes, SQLite also recognizes literals in double quotes if there is no corresponding identifier.Ĭreated in the last 90’s, co-founders David Azmark and Michael ‘Monty’ Widenius saw MySQL grow to be one of the most popular database management systems.

The built-in date and time functions can then recognize and use dates and times stored in one of these formats. Instead, it interprets dates from data that is inserted as a text in ISO-8610 format, as an integer in Unix time or as a real value in Julian Day number.

SQLite does not have an explicit DATETIME data type.

The ability to use ‘TRUE’ or ‘FALSE’ as aliases for 1 or 0 was just adopted in version 3.23.0 that was released in April.

The language does not have booleans as a built-in data type.

In addition to this, SQLite doesn’t truncate strings that are longer than what is defined.

For example, if an integer were imported as ‘452’, then SQLite would convert this value to an integer. Due to this, the system fixes some data entry errors. Unlike stricter languages, SQLite has flexible typing.Instead, you must explicitly state either a cross, inner or outer join. All of the Python versions since Python 2.5 also include SQLite.

You can find it being used at Airbus for its flight software for the A350 XWB aircrafts or in Adobe for its application file format in Photoshop Lightroom. The language is an effective option for projects with embedded devices, application file formats, websites with low to moderate traffic, data analysis and others. Since 2000, an international group of developers has offered support for it however, SQLite remains in the public domain. Unlike many other database systems, SQLite does not use a separate server but rather stores the complete database in a file. Since the creation of SQL, various RDBMS have implemented their own versions of the language in their systems, leading to a wide range of systems to choose from like MySQL or PostgreSQL with a small learning curve to each. The American National Standards Institute (ANSI) and the International Standards Organization (ISO) later published standards for the language for widespread reference. It has now become the standard for database systems over the past few decades.

Codd’s paper in 1970, SQL, or Structured Query Language, was later commercialized by Oracle in 1979. To simplify this process, I’ve compiled a list of some of the more peculiar and important differences between MySQL, PostgreSQL, and SQLite, all of which are widely used relational database management systems (RDBMS).īut first, what is SQL? Originally developed by IBM Corporation, Inc. How many times has one switched between Python to Java, resulting in constant backspaces to correct missing semicolons and other syntax idiosyncrasies to appease stubborn compilers? As with any language, SQL implementations also have their own quirks and tricks that can lead to irritating troubleshooting when syntax differences lead to undefined behavior or inaccuracies, yet the nature of data science demands a competency in switching between database management systems to meet project requirements.
