varbinary

I wrote a small VBA procedure to test uploading and downloading of files as binary data into and out of a VarBinary column in SQL Server using ADO. The upload process appears to work, but I cannot get the download process to work. I believe the output parameter for VarBinary is setup incorrectly, but I cannot find any documentation on how to do it correctly. I get run-time error 3708 "Parameter object is improperly defined. Inconsistent or incomplete information was provided." at line .Parameters.Append .CreateParameter("@myblob", adVarBinary, adParamOutput) Update : SELECT ? = myblob FROM bin

Just a quick question.. Out of two options mentioned below, how to store to varbinary column in MySQL? public_key = '67498930589635764678356756719' or public_key = 67498930589635764678356756719 Will the second method work? I am into an emergency moment working on a production server and didn't want to experiment on it. Thank you for any help. Printable data can be inserted using quotes. Non-printable data can be inserted using hexadecimal values. I.e.: INSERT INTO Table(VarBinaryColumn) VALUES('Printable data') -- Will be stored as binary representation using the charset of the operating

What is the max size of a file that I can insert using varbinary(max) in SQL Server 2008 R2? I tried to change the max value in the column to more than 8,000 bytes but it won't let me, so I'm guessing the max is 8,000 bytes, but from this article on MSDN , it says that the max storage size is 2^31-1 bytes: varbinary [ ( n | max ) ] Variable-length binary data. n can be a value from 1 through 8,000. max indicates that the maximum storage size is 2^31-1 bytes. The storage size is the actual length of the data entered + 2 bytes. The data that is entered can be 0 bytes in length. The ANSI SQL

I'm looking for a way for retrieving Entity Data Model ( EDM ) from __MigrationHistory table using only T-SQL (so anyone, using Microsoft SQL Server Management Studio only, could do the same). I want to have a valid BASE64 string value. I don't want to fully decompress it to EDMX . I don't want to get it from *.resx migration file. When I select whole __MigrationHistory in SSMS, Model column value is like following

I need to store binary files in a varbinary(max) column on SQL Server 2005 like this: FileInfo FileInfoId int, PK, identity FileText varchar(max) (can be null) FileCreatedDate datetime etc. FileContent FileInfoId int, PK, FK FileContent varbinary(max) FileInfo has a one to one relationship with FileContent. The FileText is meant to be used when there is no file to upload, and only text will be entered manually for an item. I'm not sure what percentage of items will have a binary file. Should I create the second table. Would there be any performance improvements with the two table design? Are

Ok, the problem is that there's a merger or join that needs to be done on 2 tables. One has file content stored as an [image] type or varbinary(max), the other has the file content stored as a hex string. if I upload the same content into both tables the content as string (bytearray to string) would look like like this... 'application/vnd.xfdl;content-encoding="base64-gzip" H4sIAAAAAAAAC+y9e1fjONI4/H9/Cg173idwFgIJl+5m6MzPJAayE+KsnXQPs8+cHJMY8HZi57ET aObMh3918UW2Jcdyrmbg7E7HtqpUpSqVSqWSdPHLj/EIPBuOa9rWl51K+WgHGNbAHprW45edpqYc fPp0+vmgsvNL7cPFb1eNFoDlLffLztN0Ojk/PHx5eSl3Zo4hDx

Basically I am trying to give a user a certain password so I can test some functionality on a system, as I only have our admin account and I can't play with that I am just picking a random account so I can do my testing. So here is my attempt at an update: UPDATE dbo.Login SET Salt=CAST('bPftidzyAQik' AS VARBINARY), Password=CAST('0x2B89C2954E18E15759545A421D243E251784FA009E46F7A163926247FDB945F85F095DBB1FFF5B2B43A6ADAE27B8C46E176902412C4F8943E39528FF94E0DD5B' AS VARBINARY) WHERE LoginID=10947 It runs fine however the code in the database looks japanese for one and the syntax for the other

I have a table which has an IDENTITY field and a VARBINARY(MAX) field in it. Is there any way I could dump the content of each VARBINARY(MAX) field to the filesystem (eg. c:\temp\images )? Table schema: PhotoId INTEGER NOT NULL IDENTITY Image VARBINARY(MAX) NOT NULL DateCreated SMALLDATETIME Output: c:\temp\images\1.png c:\temp\images\2.png c:\temp\images\3.png ... etc... What is the best way to approach this? I've figured it out thanks to this post ... SET NOCOUNT ON DECLARE @IdThumbnail INTEGER, @MimeType VARCHAR(100), @FileName VARCHAR(200), @Sqlstmt varchar(4000) DECLARE Cursor_Image
