What are the principles of sql?

SQL is used to look at and update data. The primary commands are SELECT, UPDATE, INSERT, DELETE. As programming topics go, basic SQL is as easy to master as anything.

You just have to know the basics of the database structre and how the data is stored. Belive me its not difficult.

Construct your SQL statement from inside the SP and use EXEC command to run it. Suppose you have parameters @ColumnName, @TableName and @number, the SP is like this:\n\n-- declare the sql variable to hold the sql statement\nDECLARE @Sql Varchar(50)\n\n-- construct the sql command using your parameters\nSET @Sql = 'SELECT ' +@ColumnName +'+' +CAST(@Number As Varchar) +' FROM ' +@TableName\n\n-- execute the sql\nEXEC (@Sql)

Companies use Oracle more than Microsoft, although it'd be good to get some experience with SQL.  I've used both, and never seen any real huge difference between the two.  The coomands are generally the same, the logic is generally the same.

http://dev.mysql.com/doc/refman/5.0/en/sql-syntax.html\nYour best bet is to Start with MySQL, which is an Open Source Implementation, then learn SQL and then Database Design, and shortly after you will be a full fledged DBA

a database is a software program used to store, manage and retrieve data. There are many types of databases, the most common being a relational database system (RDBMS).\n\nAn RDBMS uses the concept of tables and rows to store data. A table is made up of columns each of which has a specific data type. A data type may be text, number, date & time, single character. The RDBMS has rules that database administrator (DBA) can apply which regulate how the data is stored. \n\nThere is a basic set of rules which a well designerd RDBMS will follow. This set of rules is called "Normalization" or normalizing the database. It is a very large topic. But, essentially, they are the best practices method for designing how database tabes are designed, which data goes into which tables, etc.\n\nA database has a special language used to manage tables, columns,security and the data within the database. This language is called Structured Query Language (SQL). Some people pronouce SQL as "sequel". Within SQL there are commands to manipulate data. This is know as the DML set of commands. There is also the DDL or data defintion language set of commands. DDL is used for creating tables, columns, indexes, triggers, permissions, etc.\n\nOrcale, MS Sql Server, MS Aceess, MySql, DB2 are all examples of modern RDBMS systems. They all support the standard ANSI SQL language. however, each RDBMS also has their own subtle spin on the language. \n\nhope this helps

when you have specific questions like that, make the search (yahoo/google) your friend.  That's how all programmers get quick information.  Do you have to use access?  SQL Server is so much easier to use and more robust.

What do you mean?\nMaybe "SQL command with two criteria?"?\n\nIn this case if you mean the condition "WHERE" you joint each condition with "AND".\nExample:"SELECT * FROM table WHERE field0 = 'value0' AND field1 = 'value1';"

It would be helpful to know what version of SQL you want.\n\nFor Transact-SQL (Microsoft): http://msdn.microsoft.com\n\nFor MySQL: http://forums.mysql.com/\n\nFor PL/SQL (Oracle): http://education.oracle.com/

If it's a standard .sql file, you should be able to split it. This would break transactions, but depending on the statements in the file this may not be an issue.

Well your question is not clear.But if you wanna know what a database system is ...\nA database keeps all possible information in the form of records that are normally maintained in the form of tables.\nThere are some really advance techniques of handling these databases using Oracle or SQL server or DB2 etc.\nIf you want to do some basic operations you'll have to learn the language called SQL(Structured Query Language) which is language for the manipulation of databases.\nThese systems are normally the backend support for systems whose front ends are visible to you in the form various Web Applications,Web services and other Desktop based applications.

SQL : Structured Query Language, is the most popular computer language used to create, modify and retrieve data from relational database management systems. The language has evolved beyond its original purpose to support object-relational database management systems. It is an ANSI/ISO standard.\n \nT-SQL : Short for Transaction-SQL an extended form of SQL that adds declared variables, transaction control, error and exception handling and row processing to SQL’s existing functions. \n\nMS SQL : Microsoft SQL and its Programing Software from Microsoft
