Analytics Platform System (PDW)
Generates any error message and raises a processing error due to the session. RAISERROR can either refer to the actual custom message stored in the viewcollection sys.messages, or dynamically create a message. The message is returned as an error queue message to the calling application or to the associated CATCH block of a TRY … CATCH construct. Instead, new applications should use THROW .
Syntax
- Syntax for SQL Server and Azure SQL Database RAISERROR (msg_id , Severity, period [, Argument [, ...] n]) [The MIT Approach [, ... n]]
- syntax for Azure Synapse Analytics and Parallel Data Warehouse RAISERROR (Msg_str , gravity, state [, Argument [, ...] n]) [With option [, ... d]] A
Arguments
msg_id
is a user-defined error impact count that is stored in a specific sys.messages view using sp_addmessage. Error numbers for custom error messages must be greater than 50000. If msg_id is not specified, RAISERROR appends the error message with an array of 50000 errors.
msg_str
This is a custom message with a format similar to the printf function in some C library standards. The error message can be up to 2047 characters long. If the message contains 2048 or more system types However, only the first 2044 will be displayed and therefore an ellipsis will be added to indicate which message was usually truncated. Note which parameter to replace requires more characters than displayed in the current output, due to compatibility with internal memory. For example, the substitution parameter associated with% d set to 2 generates only one character in the message number, but also internally requires three characters much more storage space. This memory requirement reduces the number of characters available for dot output. Msg_str
If specified, RAISERROR will issue each error message with an error number referring to 50000. Yes
msg_str is a string in all built-in conversion specifications. Each transform choice determines how the value in the select list is formatted and is placed in each field at the position of the transform speed specification in msg_str. The conversion specifications that create this format are:
Code that identifies the location and reason for the replaced value.
| Code | Justification prefix | Description |
|---|---|---|
| – (less) | Left Aligned | Usually aligns the argument value within the specified field width. |
| + (more) | Sign Prefix | Use a plus (+) and / or a minus sign in front of each argument value. If (-) the value comes from all signed types. |
| 0 (zero) | zero padding | The final result is added to zero, the minimum width is simply achieved. If 0 and minus are displayed, the warning sign (-), 0 is ignored. |
| # (number) | 0x prefix for hexadecimal type x or X | When used with the format o, x, or X, the number prefixes the character code (#) to any nonzero value with 0, 0x, or 0X. If d, i, or oughout is preceded by a numeric indication flag (#), this flag is ignored. |
| ‘lol (empty) | space | Add blank sites to the output value if the value is signed and beneficial. It will be ignored if it has a gratitude indicator with a plus sign (+). |
is an integer specifying the minimum wIrina of the category in which the argument value is embedded. If the length of the price argument is equal to or greater than the density, the value is printed without padding. If the value is shorter than steep, the value is padded to the width specified by width.
An asterisk (*) means that the width is specified by the accompanying argument in the list argument, which has an integer value.
The maximum character rate, taken from the advantages of arguments for string values. For example, if this string is five characters long and the precision must be 3, only the first three characters of the string value are used.
For integer aspects, the precision is at least equal to the number of numbers printed.
An asterisk (*) means that reliability is indicated by the associated argument when it comes to an argument list that must be an integer.
When used with the character types c, i, o, s, x, X, or and, as well as u, Shortint (h) or Longint (l) generates values.
| Type specification | Represents |
|---|---|
| d or i | Signed integer |
| or | Eight Unsigned riches |
| with | string |
| you | Unsigned integer |
| x or X | Unsigned Hex |
@variable_locale
A variable associated with any valid character data type that contains a formatted string, such as msg_str. @local_variable must also be a char varchar, otherwise it must be possible to convert it to these datatypes without a doubt.
Serious
Whether the severity is all associated with this message. When you use when msg_id to trigger a custom message generated with sp_addmessage, the severity specified with RAISERROR overrides the severity specified in sp_addmessage.
The WITH LOG option is typically required for severity levels 19-25. Severity values less than 0 are interpreted as. A severity level above 25 is considered 25.

You can specify -1 to change the severity associated with the current error, as shown in the following example.
RAISERROR (15600, -1, -1, 'mysp_CreateCustomer');
Msg 15600, Level 15, State 1, Line 1An invalid parameter or op was specifiedtion, procedure for mysp_CreateCustomer.
Status
An integer from 0 to 254. Negative values up to the norm of 1. Principles greater than 255 should not be used.
If I were to say that the same custom error occurred in multiple places, using a unique status number for each location can help determine which aspect of the code is causing the errors.
argument
Most of the parameters are used to override parameters defined in msg_str or the message that corresponds to msg_id. It can also be 0 to replace additional parameters, but the total choice of replacement parameters should not exceed 20. Each replacement parameter can be a local offset or one of the following data types: tinyint, smallint, int, char, varchar, nchar, binary, nvarchar, possibly , varbinary. Other data types are ignored.
Option
This is a configurable error and can be any of the beliefs following the table.

Speed up your computer's performance now with this simple download. RAISERROR is a SQL Server error moving operator that generates an error message and initiates error handling. RAISERROR can either create its own message here in the sys. A view or idea of a message catalog can create messages dynamically.
A common trick is probably a forced division by 0. This results in an error and interrupts the actual reading of the person evaluating the game.
RAISERROR (message_id, severity, state [, argument [, n]]) [With resolution [, n]];EXEC sp_addmessage @msgnum means 50005, @severity = 1, @msgtext means Custom Error Message;
