Connect to sqlserver through osql

<Doctype HTML public-wcdtd XHTML stricten httpwwwworgtrxhtmldtdxhtml-strictdtd>

The sqlserver2000 query analyzer only supports 64 K scripts. Therefore, it is impossible to import data using insert. SQL scripts. You can use the osql command to connect to the script file and execute the script.
Usage: osql [-u logon id] [-P Password]
[-S server] [-H host name] [-e trusted connection]
[-D use the database name] [-l logon timeout value] [-T query timeout value]
[-H title] [-s column separator] [-W column width]
[-A packet size] [-e echo input] [-I allows a quoted identifier]
[-L list servers] [-C command end] [-d odbc dsn name]
[-Q "command line query"] [-Q "command line query" and exit]
[-N delete number method] [-M error level]
[-R messages sent to stderr] [-V severity level]
[-I input file] [-O output file]
[-P print statistics] [abort batch processing when a-B error occurs]
[-X [1] disable command, [display a warning when exiting]
[-O use the old iSQL to disable the following items]
<EOF> Batch Processing
Auto Adjust console width
Wide message
The default error levels are-1 and 1.

Command Line operations are sometimes more efficient than using the mouse in the graphic interface. Therefore, you are familiar with common command line operations. The following describes the SQL server command line tools iSQL and osql.

The iSQL utility allows you to enter Transact-SQL statements, system processes, and script files, and use DB-library to communicate with SQL Server 2000.

Osql utility allows you to enter Transact-SQL statements, system processes, and script files. The utility communicates with the server through ODBC.

& #9670; view objects in database pubs:
Use pubs
Exec sp_help

Equivalent to select table_name from user_objects of Oracle;

& #9670; when a single quotation mark is used to separate a character constant that includes an embedded single quotation mark, two single quotation marks are used to indicate the embedding of single quotation marks. For example:
Select 'O' Leary'
Go

Select 'o "Leary'
Go

& #9670; iSQL command description
All the statements that go enters after executing the last go command.
Reset clears all input statements.
Ed calls the editor.
!! Command to execute the operating system command.
Quit or exit () to exit iSQL.
CTRL + C ends the query without exiting iSQL.
Only when the command Terminator go (default), reset, Ed ,!! Exit, quit, and CTRL + C can be recognized only when a row starts (followed by the iSQL prompt. ISQL ignores any content entered after these keywords in the same row.
