sqlBlobUtil


1) make blob compress, uncompress, retriving, updating, inserting as simple as normal select
statement.
2) support multiple blob fields in 1 table
support insert, retrive, update from file or memory
3) sample call
RetrieveBlob(ADODB.Connection, sSql, sOutput) As String : retrieve single blob from database,
RetrieveBlobToFile(ADODB.Connection, sSql, blobfiles, sOutput,recordSet) As recordCount
InsertBlobFromFile(ADODB.Connection, sSql, vBlobfiles)
vBlobfiles as array of files or fileName
InsertBlob ADODB.Connection, sSql, vBlobs
vBlobs as string or array of string
UpdateBlobFromFile ADODB.Connection, sSql, vBlobfiles
UpdateBlob ADODB.Connection, sSql, vBlobs
sample input sql clause:
insert into sTableName values(1,"ke,dfs,y",?,?,getdate())
insert into sTableName values(1,'ke,df"s,y',?,?,22-May-1992)
select a, c from sTableName where key = 1
update parameterxml set a='ere',b='?' where d ="dfds"
NOTE!) compress and uncompress are invisible to user
!!!compress tool is not publish with this tool.
(in order to use) comment out the compress part or replace with your own compress tool

Original Author: hwa ying lee
