Sys.sql_Module does not give full defination of store procedure

Question

I want to get a defination of a store procedure by using sys.sql_Module
Beflow is the query i use 
SELECT  
@spTxt =ISNULL(smsp.definition, ssmsp.definition)) 
FROM sys.all_objects AS sp
LEFT OUTER JOIN sys.sql_modules AS smsp ON smsp.object_id = sp.object_id
LEFT OUTER JOIN sys.system_sql_modules AS ssmsp ON ssmsp.object_id = sp.object_id
WHERE (sp.type = N'P' OR sp.type = N'RF' OR sp.type='PC')and(sp.name=@SpName 
and SCHEMA_NAME(sp.schema_id)=@SchemaName)
@SchemaName = SCHEMA 
ANd @SpName = Store procedure Name.
This query does not give me complete store procedure.
Is there any other table i need to join and I can get full defination?
Thank you.

You're confusing what's being stored vs what's being displayed. The full proc is being stored in the definition column. It's just that SSMS won't display the full content of the cell.
The following is a proc that we use to overcome this situation... (I have no clue who the original author is)
CREATE PROCEDURE [dbo].[LongPrint]
@String NVARCHAR(MAX)
AS
Example:
exec LongPrint @string =
'This String
Exists to test
the system.'
/* This procedure is designed to overcome the limitation
in the SQL print command that causes it to truncate strings
longer than 8000 characters (4000 for nvarchar).
It will print the text passed to it in substrings smaller than 4000
characters. If there are carriage returns (CRs) or new lines (NLs in the text),
it will break up the substrings at the carriage returns and the
printed version will exactly reflect the string passed.
If there are insufficient line breaks in the text, it will
print it out in blocks of 4000 characters with an extra carriage
return at that point.
If it is passed a null value, it will do virtually nothing.
NOTE: This is substantially slower than a simple print, so should only be used
when actually needed.
DECLARE @CurrentEnd BIGINT, /* track the length of the next substring */
@offset TINYINT /*tracks the amount of offset needed */
SET @string = REPLACE( REPLACE(@string, CHAR(13) + CHAR(10), CHAR(10)) , CHAR(13), CHAR(10))
WHILE LEN(@String) > 1
BEGIN
IF CHARINDEX(CHAR(10), @String) BETWEEN 1 AND 4000
BEGIN
SET @CurrentEnd = CHARINDEX(CHAR(10), @String) -1
SET @offset = 2
END
ELSE
BEGIN
SET @CurrentEnd = 4000
SET @offset = 1
END
PRINT SUBSTRING(@String, 1, @CurrentEnd)
SET @string = SUBSTRING(@String, @CurrentEnd+@offset, 1073741822)
END /*End While loop*/
GO
To use the proc, you'd do something like this...
DECLARE @sql VARCHAR(MAX)
SELECT @sql = sm.definition FROM sys.sql_modules sm WHERE sm.object_id = 892230629
EXEC dbo.LongPrint @sql
