Find all columns of a certain type in all tables in a SQL Server database
You can use following query to return fields
SELECT table_name [Table Name], column_name [Column Name]
FROM information_schema.columns where data_type = 'NTEXT'
Find all columns of type nvarchar(max) in all tables in a SQL Server database
The character_maximum_length will be -1 for max.
select
table_name as [Table Name]
, column_name as [Column Name]
from information_schema.columns
where data_type = 'nvarchar'
and character_maximum_length=-1
Search all tables, all columns for a specific value SQL Server
I've just updated my blog post to correct the error in the script that you were having Jeff, you can see the updated script here: Search all fields in SQL Server Database
As requested, here's the script in case you want it but I'd recommend reviewing the blog post as I do update it from time to time

SQL Server query to get data type for all columns in table?
SELECT c.name,
c.max_length,
c.precision,
c.scale,
c.is_nullable,
t.name
FROM sys.columns c
JOIN sys.types t
ON c.user_type_id = t.user_type_id

How to find column names for all tables in all databases in SQL Server
Try this:
select
o.name,c.name
from sys.columns c
inner join sys.objects o on c.object_id=o.object_id
order by o.name,c.column_id
With resulting column names this would be:
select
o.name as [Table], c.name as [Column]
from sys.columns c
inner join sys.objects o on c.object_id=o.object_id
--where c.name = 'column you want to find'
order by o.name,c.name
Or for more detail:
SELECT
s.name as ColumnName
,sh.name+'.'+o.name AS ObjectName
,o.type_desc AS ObjectType
,CASE
WHEN t.name IN ('char','varchar') THEN t.name+'('+CASE WHEN s.max_length<0 then 'MAX' ELSE CONVERT(varchar(10),s.max_length) END+')'
WHEN t.name IN ('nvarchar','nchar') THEN t.name+'('+CASE WHEN s.max_length<0 then 'MAX' ELSE CONVERT(varchar(10),s.max_length/2) END+')'
WHEN t.name IN ('numeric') THEN t.name+'('+CONVERT(varchar(10),s.precision)+','+CONVERT(varchar(10),s.scale)+')'
ELSE t.name
END AS DataType
,CASE
WHEN s.is_nullable=1 THEN 'NULL'
ELSE 'NOT NULL'
END AS Nullable
,CASE
WHEN ic.column_id IS NULL THEN ''
ELSE ' identity('+ISNULL(CONVERT(varchar(10),ic.seed_value),'')+','+ISNULL(CONVERT(varchar(10),ic.increment_value),'')+')='+ISNULL(CONVERT(varchar(10),ic.last_value),'null')
END
+CASE
WHEN sc.column_id IS NULL THEN ''
ELSE ' computed('+ISNULL(sc.definition,'')+')'
END
+CASE
WHEN cc.object_id IS NULL THEN ''
ELSE ' check('+ISNULL(cc.definition,'')+')'
END

FROM sys.columns s
INNER JOIN sys.types t ON s.system_type_id=t.user_type_id and t.is_user_defined=0
INNER JOIN sys.objects o ON s.object_id=o.object_id
INNER JOIN sys.schemas sh on o.schema_id=sh.schema_id
LEFT OUTER JOIN sys.identity_columns ic ON s.object_id=ic.object_id AND s.column_id=ic.column_id
LEFT OUTER JOIN sys.computed_columns sc ON s.object_id=sc.object_id AND s.column_id=sc.column_id
LEFT OUTER JOIN sys.check_constraints cc ON s.object_id=cc.parent_object_id AND s.column_id=cc.parent_column_id

EDIT
Here is a basic example to get all columns in all databases:
DECLARE @SQL varchar(max)
SET @SQL=''
SELECT @SQL=@SQL+'UNION
select
'''+d.name+'.''+sh.name+''.''+o.name,c.name,c.column_id
from '+d.name+'.sys.columns c
inner join '+d.name+'.sys.objects o on c.object_id=o.object_id
INNER JOIN '+d.name+'.sys.schemas sh on o.schema_id=sh.schema_id
'
FROM sys.databases d
SELECT @SQL=RIGHT(@SQL,LEN(@SQL)-5)+'order by 1,3'
--print @SQL
EXEC (@SQL)
EDIT SQL Server 2000 version
DECLARE @SQL varchar(8000)
SET @SQL=''
SELECT @SQL=@SQL+'UNION
select
'''+d.name+'.''+sh.name+''.''+o.name,c.name,c.colid
from '+d.name+'..syscolumns c
inner join sysobjects o on c.id=o.id
INNER JOIN sysusers sh on o.uid=sh.uid
'
FROM master.dbo.sysdatabases d
SELECT @SQL=RIGHT(@SQL,LEN(@SQL)-5)+'order by 1,3'
--print @SQL
EXEC (@SQL)
EDIT
Based on some comments, here is a version using sp_MSforeachdb:
sp_MSforeachdb 'select
''?'' AS DatabaseName, o.name AS TableName,c.name AS ColumnName
from sys.columns c
inner join ?.sys.objects o on c.object_id=o.object_id
--WHERE ''?'' NOT IN (''master'',''msdb'',''tempdb'',''model'')
order by o.name,c.column_id'
SQL server query to get the list of columns in a table along with Data types, NOT NULL, and PRIMARY KEY constraints
To avoid duplicate rows for some columns, use user_type_id instead of system_type_id.
SELECT
c.name 'Column Name',
t.Name 'Data type',
c.max_length 'Max Length',
c.precision ,
c.scale ,
c.is_nullable,
ISNULL(i.is_primary_key, 0) 'Primary Key'
FROM
sys.columns c
INNER JOIN
sys.types t ON c.user_type_id = t.user_type_id
LEFT OUTER JOIN
sys.index_columns ic ON ic.object_id = c.object_id AND ic.column_id = c.column_id
LEFT OUTER JOIN
sys.indexes i ON ic.object_id = i.object_id AND ic.index_id = i.index_id
WHERE
c.object_id = OBJECT_ID('YourTableName')
Just replace YourTableName with your actual table name - works for SQL Server 2005 and up.
In case you are using schemas, replace YourTableName by YourSchemaName.YourTableName where YourSchemaName is the actual schema name and YourTableName is the actual table name.
Get column names of all tables in SQL
You can use INFORMATION_SCHEMA.COLUMNS:
select c.*
from INFORMATION_SCHEMA.COLUMNS c;
This has name, type, and a lot of other information for all tables in a database -- note, not on a server but in a database.
How Find a value as any Data Type by searching all tables in SQL Server
You can try below query. I have tried and found working awesomely.
DECLARE @SearchStr nvarchar(100)
SET @SearchStr = '201902'

I have found this in below link. You will also find a store procedure to do so.
