I originally imported these files using the Import and Export Wizard from a fixed width file. I had planned to have the field in question, firms, as numeric (8,0) but I was getting an error about data type conversion failed. So I changed it varchar (20) and it imported successfully. There are roughly 1.48 million rows in the table.
Now, I am trying to change it back to numeric (8,0) or INT and both give me an arithmetic overflow error. I used the following code to find the maximum length of values in the column
select(max(len(firms)) from dbo.tablename and it returned a value of 5.
Any insights on how to remedy this?

I'm struggling a bit in the best way to describe this question. I have a set of zip code values that are currently stored as a varchar data type. I am trying to clean the column and store it in a different table with an int data type. Running CAST on the column gives me a conversion error:
Msg 245, Level 16, State 1, Line 52 Conversion failed when converting the nvarchar value '６００９９' to data type int.
Upon narrowing this down, I find this record with a strange font on row 425. I've never seen anything like this nor can I find much about it from a google search. All other records will convert just fine if I exclude this particular record. Can anyone point me in a direction here?
Nvarchar column allowed a unicode value to be stored with characters meant to represent ASCII values.
I have a stored procedure; when I execute it, I get an error
Arithmetic overflow error converting numeric to data type varchar
Is there is way to find the column that caused this issue? I have the T-SQL. Checking columns one by one is very tedious for us because we have lots of columns (legacy system).
There are many options to address and prevent the error, based on the prodedure's T-SQL, but the answer to your question is "No". MS Does not make the offending column information available.

I currently have a table that is importing data from provided CSV's on a regular basis. The issue is that I have 6 columns with data type Decimal(5,2) and are nullable, when I import a file that doesn't report any numbers back it appears as ",,,,connectionfailed,,,," within these commas are usually the numbers i'm expecting to import into the table.
When SSIS attempts to import these "blank" csv's I get the following error
Error: 2014-08-04 23:45:01.31 Code: 0xC020901C Source: Data Flow Task OLE DB Destination [9] Description: There was an error with input column "LaunchBBTime" (85) on input "OLE DB Destination Input" (22). The column status returned was: "The value could not be converted because of a potential loss of data.". End Error
Now when I change all the colums to varchar for testing purposes it imports the blank spaces without a problem, the 2nd issue with this is that SSRS cant calculate averages (in this case for performance) from varchar fields.
My question is can I properly get SSIS to import the blank columns into decimal(5,2) fields without needing to modify the datatypes?
It looks like the problem is being caused by spaces i.e. ", ," instead of ",," otherwise the datatype will set the field to its default value (in the case of decimal "0" or NULL, depending on the "retain null values from the source" property). If this is the case, probably the safest and less performance-expensive solution is passing the csv through a pre-process to remove the white spaces.
Pull the columns in as varchar, then in a Derived Column Transformation, create new decimal columns that are populated with something like the following...
LEN(LTRIM([InputValue]))==0 ? NULL(DT_NUMERIC,5,2) : (DT_NUMERIC,5,2)[InputValue]
I am using a bulk insert to import data from a CSV file. One of the fields is a number, and I import it as a DECIMAL(4,3). However, this data file has a few values where the number is "3.2342e-05". This obviously throws an error since this is a char. How can I convert this number to zero? For my purposes, I plan to consider any number that small as a zero anyway.
I figure that I will be importing the data into a temp table (staging table) first, so that I can clean it up in there, and then I will be inserting it from there into my final table.
SQL Server 2008
EDIT: One thing I am considering is importing the data as a char and then converting the column type, and then using a CASE statement to set anything greater than 1 to a zero. This field should never be greater than 1, which is why I am able to do this.
This is recognised as float, so you can double CAST via float
We get sometimes the following error from our partner's database:
<i>ORA-01438: value larger than specified precision allows for this column</i>
The full response looks like the following:
<?xml version="1.0" encoding="windows-1251"?>
<response>
<status_code></status_code>
<error_text>ORA-01438: value larger than specified precision allows for this column ORA-06512: at "UMAIN.PAY_NET_V1_PKG", line 176 ORA-06512: at line 1</error_text>

What can be the cause for this error?
The number you are trying to store is too big for the field. Look at the SCALE and PRECISION. The difference between the two is the number of digits ahead of the decimal place that you can store.
select cast (10 as number(1,2)) from dual
*
ERROR at line 1:
ORA-01438: value larger than specified precision allowed for this column
select cast (15.33 as number(3,2)) from dual
*
ERROR at line 1:
ORA-01438: value larger than specified precision allowed for this column
Anything at the lower end gets truncated (silently)
select cast (5.33333333 as number(3,2)) from dual;
CAST(5.33333333ASNUMBER(3,2))
-----------------------------
5.33
The error seems not to be one of a character field, but more of a numeric one. (If it were a string problem like WW mentioned, you'd get a 'value too big' or something similar.) Probably you are using more digits than are allowed, e.g. 1,000000001 in a column defined as number (10,2).
Look at the source code as WW mentioned to figure out what column may be causing the problem. Then check the data if possible that is being used there.
Further to previous answers, you should note that a column defined as VARCHARS(10) will store 10 bytes, not 10 characters unless you define it as VARCHAR2(10 CHAR)
[The OP's question seems to be number related... this is just in case anyone else has a similar issue]
This indicates you are trying to put something too big into a column. For example, you have a VARCHAR2(10) column and you are putting in 11 characters. Same thing with number.
This is happening at line 176 of package UMAIN. You would need to go and have a look at that to see what it is up to. Hopefully you can look it up in your source control (or from user_source). Later versions of Oracle report this error better, telling you which column and what value.
FYI:
Numeric field size violations will give
ORA-01438: value larger than specified precision allowed for this column
VARCHAR2 field length violations will give
ORA-12899: value too large for column...
Oracle makes a distinction between the data types of the column based on the error code and message.
One issue I've had, and it was horribly tricky, was that the OCI call to describe a column attributes behaves diffrently depending on Oracle versions. Describing a simple NUMBER column created without any prec or scale returns differenlty on 9i, 1Og and 11g
From http://ora-01438.ora-code.com/ (the definitive resource outside of Oracle Support):
ORA-01438: value larger than specified precision allowed for this column
Cause: When inserting or updating records, a numeric value was entered that exceeded the precision defined for the column.
Action: Enter a value that complies with the numeric column's precision, or use the MODIFY option with the ALTER TABLE command to expand the precision.
http://ora-06512.ora-code.com/:
ORA-06512: at stringline string
Cause: Backtrace message as the stack is unwound by unhandled exceptions.
Action: Fix the problem causing the exception or write an exception handler for this condition. Or you may need to contact your application administrator or DBA.
It might be a good practice to define variables like below:
v_departmentid departments.department_id%TYPE;
NOT like below:
v_departmentid NUMBER(4)
It is also possible to get this error code, if you are using PHP and bound integer variables (oci_bind_by_name with SQLT_INT).
If you try to insert NULL via the bound variable, then you get this error or sometimes the value 2 is inserted (which is even more worse).
To solve this issue, you must bind the variable as string (SQLT_CHR) with fixed length instead. Before inserting NULL must be converted into an empty string (equals to NULL in Oracle) and all other integer values must be converted into its string representation.
