I have a table (table1) that has a bunch of fields....
[field1]
[field2]
[field3]
[field4]
[field5]
None of these fields are unique, but if I combine them, then they are
unique.
I know there is a way to make multi-field primary keys, but when I try
I get an that field1 is not unique, which I already know,
How can I make a multi-field primary key?
thanks
Hi all,
I have been pulling my hair trying to figure out what the guys at microsoft were thinking when creating the ADOX library. I have an access table that is syncronized with a SQL server. The table has a primary key with two columns [User] and [Program]. The SQL Server has both columns in as the primary key columns and I have a syncronization mechanism that is responsible for several things, one of which is to recreate the Access data structure. All works well for all tables except this one. I have tried to create the multi-column key in several ways, none that worked. Let me show you what I am doing:
CatalogClass catDCDLocal;
Column c;
catDCDLocal = new CatalogClass();
catDCDLocal.let_ActiveConnection(dbAccess.buildConnectionString(Settings.CattDCDLocalPath, Settings.SecurityDBPath, s.UserID, s.Password));
foreach (Table tbl in catDCDLocal.Tables) {
if (tbl.Name == "Users") {
/* This is retarded so need to clean up... Users table has a primary key consisting of 2 columns */
for (int i = tbl.Keys.Count - 1; i >= 0; i--) { //remove the keys
tbl.Keys.Delete(i);
}
for (int i = tbl.Indexes.Count - 1; i >= 0; i--) { //remove the indexes
tbl.Indexes.Delete(i);
}
tbl.Keys.Append("PrimaryKey", KeyTypeEnum.adKeyUnique, "User", "", "");
tbl.Keys[0].Columns.Append("Program", DataTypeEnum.adWChar, 6);
}
}
I have also tried:
tbl.Keys.Append("PrimaryKey", KeyTypeEnum.adKeyUnique, "User", "", "");
//tbl.Keys[0].Columns.Append("Program", DataTypeEnum.adWChar, 6);
Key k = tbl.Keys[0];
Column col = tbl.Columns["Program"];
//col.ParentCatalog = catDCDLocal;
k.Columns.Append(col, DataTypeEnum.adWChar, 6);
Nothing works for me ;-(
here is what i am wanting to do but is it possible to use multi fields with an IN statement?

WHERE usac_code = 'O/W')
I have a multi value field into which I have placed several different values. I wish to compare a value that is entered by the user with the multi value field, to find if the value entered is there. I am assuming ( and also hoping) that I can use DLookUp to do this. At the moment I get all of the multi values returned by DlookUp and they are separated by commas and the value that I want to find is in there. However this is giving me an error because of the separating commas. How can I isolate/extract the value that I want so that I can make a comparison ? Is it something like MyFieldName.Value?

Trying to get a multi field grouping to print.
Client + Req Number + Status
Client and status are nvarchar fields
Req Number is an int.

Does anyone has an idea on creating a new field in a table with more then say 10000 rows already in that table, and making that new field as primary key field. None of the fields in that table are unique.

Hi,
I want to find out the primary key field name of the table using system table information i.e. sysobjects, syscolumns etc.

Hello,
I have an app that is connected to SQL 2005 express edition.
In the DB there is a table that has an auto incremental primary key
What I want is, I want to get a new value for that auto incremental field before sending the new record's date to the DB to be stored. So I can display the new record's ID in my app's interface
So is there something in SQL server like SEQUENCE in oracle.
Thanks in advance.

Hi,
When I try execute one query in SQL 2k5, with alias in order by clausule, I retrieve the follow message:
Server: Msg 4104, Level 16, State 1, Line 1
The multi-part identifier "alias.fields" could not be bound.
Where alias is a any alias and, fields is a field of the table with alias.
Already exists one fix to patch this?
Thanks
Greetings,
I have several reports for which the user has asked to have an optional muti-value parameter. They want to be able to select zero, one, many, or all values in the parameter list. The parm list is created through a query and the values are not static.
I would like to allow the user to leave the muti-value field empty if they want to allow all values to appear on the report. I've read some discussion about populating a multi-value default with the same query that produces the multi-value list values - presto, everything is selected. However, this is not a desirable solution for me because I "echo" the users parameter selections in the report heading. Selecting all values (and some parms have a lot of values) would cause the "parm feedback" section to grow large and unreadable.
In short, I don't want to tell the user they have to select everything when they really want to select nothing.
Is there any way to have a muti-value parm that won't insist the user select one or more values?
Thanks,
BCB
I need to insert a row of data and return the value of the primary key id of the row.
I thought that something like this would work
int Key = (int)command.ExecuteScalar();
where command is SqlCommand object.
It doesn't work, maybe I've misunderstood the usage of ExecuteScalar.
I want to use the Identity field (increment 1,1) as a primary key andhave a unique constraint on my other field which is of type char.I am worried that related data in other tables may lose referntialintegrity if records in the ID table get messed up and need to bere-entered.Can you please advice on best way to do this. I definitely need anumeric id field because it makes the joins and queries so muchfaster.

I was just wondering on a very simple database table with lets say a primary key set to columb ID and another columb lets say products, can you make the primary key automaticly increment its self whenever a new entry has been put in?For instance say I have this table set up with ID Being the primary KEY, Columb 1 = ID( INT ), Columb 2 = Products ( VarChar(50) ), and have the fields ID = 1, and products = my product.....and if a user inserts a new record say from a gridview or some sort of data entry the second ID Feild will automaticly be 2 and the products gets updated per user input.......I'm very sorry but I'm having a hard time putting this into words for some reason..umm basicly user adds something into the products feild and the ID field automaticly increments one number higher from the last one?ThanksAdam.
View 4 Replies View RelatedI'm really puzzled with this. I am new to using MS SQL and need help with the primary key. When I was using Access, I would open the database table and just enter values for the various columns, each time a new column was begun, the computer would insert a unique number there. OK, so now I am using visual studio to work on a SQL database. I created a new table and the first field I specified was "ID", I then chose it as the primary key. For default value, I tried both auto number and auto increment. These don't seem to work, as when I type values into fields and try to move to the next row, having left the ID field blank, I get an error which reads "String or Binary data may be truncated". What is going on, what do I need to do so the field automatically populates with an ID number... Some research sort of led me to the concept of a "trigger" to do this. Is this the approach. I was able to r-click on the table and I saw an option for "create trigger" or "new trigger"... How do I learn to do this, is there a generic trigger to do an auto increment of a primary key ID field?

Hello I currently have a merge replication set up with 4 subscribers. A primary field for one of my tables is set to a integer indetity.
What Ive noticed is that depending on which database I enter data into, the indentity field (primary key) is set within a certain range I.e
On Server 1 - Values start from 1 then 2,3,4 etc etc
Server 2 - 24001, 24002, 24003 etc etc
Server 3 - 46001, 46002, 46003 etc etc
Server 4 - 68001, 68002, 68003
My question is what happens when these ranges eventually conflict? Do they automatically gain a different range such as 142 001, 142 002 etc etc?
Ive tried looking in SQL Help, and a quick search here, Im just after some confirmation before I implement this to my app.
cheers

View 3 Replies View RelatedHi there,
I have been hired for a couple of weeks to investigate the performance of a sql server 2000 system.
One of the things that strikes me is that all the Primary key (identity field) fileds uses an decimal(18,0) as it's datatype.
An decimal with a precision of 18,0 takes 9 bytes for each column, while an int takes only 4 bytes and and bigint 8 bytes.
Many tables aren't that big, so the values will fit in an int datatype.
1. Is iot a good option to change the decimals columns to an int column ?
2. Many of these columns are indexed by a clustered index. Can the decimal datatype be a performance issue ?
3. sometimes they have deadlocks due page splits. Can this by reduced by changing the data types, while more data fit's into an page?
Thanks in advance,
Greetz,

I have a question on autogenerating numbers for a primary key field, "studyID," in a table€”but with a few twists.
We want studyID to be automatically generated as a 5-digit number. Additionally, we have two study sites and would like the studyIDs pertaining to the first site to begin with a 1 and StudyIDs associated with our second site to start with a 2. When we begin entering data, we will enter either a 1 or 2 in a field called, "Site." Upon entering that 1 or 2, we would like at that moment for Access to instantly autogenerate the appropriate studyID for that site and put it in the "StudyID" field. We want the very first number generated for each site to end in a 1 (10001 and 20001).
Here€™s the range of values we want our StudyIDs to be (this is to be our validation rule as well):
10001-19999 for Site 1
20001-29999 for Site 2
Your suggestions are VERY VERY WELCOME! THANKS!
I am designing a database. I want to define a automatic sequence on a table primary key field. what is the best solution for it?
I know I can enable identity property for a field, but it has some problems ( for example its seed jumps on restart and unsuccessful events)
I also can use some calculated sequences. for example I can calculate max of the filed values and after incrementing use it as key for new inserted record.
which one is better?
I have been testing my database application for a while now. As a result i have a lot of records already with their respective identity field values. What i want to do is to reset this field to 0 (zero) before i deploy the aplication. I have tried deleting all the records and entered one to see if the id will be 1 but it still starts from where it was before i deleted the records. Any ideas.
