I want to have a sharepoint lookup column, which values should not be duplicated in the destination list.
Can be duplicated in source list.
I create and deploy the list through VS solution.
Any idea?
You will need to put the following attributes on the lookup column definition
EnforceUniqueValues = "TRUE"
Indexed = "TRUE"
SPField field = list.Fields["TestCol"];
field.Indexed = true;
field.EnforceUniqueValues = true;
field.Update();

We have a storage table where we want to add a new integer column (It is in fact an enum of 3 values converted to int). We want a row to be required when:
It is an older row and the column does not exist
It is a new row and the column exists and does not match a particular value
When I just use a not equal operator on the column the old rows do not get returned. How can this be handled?
Update
Assuming a comparison always returns false for the non-existent column I tried somethinglike below (the value of the property will be always > 0 when it exists), which does not work either:
If the (Prop GreaterThanOrEqual -1) condition returns false I assume the value is null.
If not then, the actual comparison happens.
string propNullCondition = TableQuery.GenerateFilterConditionForInt(
"Prop",
QueryComparisons.GreaterThanOrEqual,
-1);
propNullCondition = $"{TableOperators.Not}({propNullCondition})";
string propNotEqualValueCondition = TableQuery.CombineFilters(
propNullCondition,
TableOperators.Or,
TableQuery.GenerateFilterConditionForInt(
"Prop",
QueryComparisons.NotEqual,
XXXX));
Note: The table rows written so far do not have "Prop" and only new rows will have this column. And expectation is the query should return all old rows and the new ones only when Prop != XXXX.
It seems that your code is correct, maybe there is a minor error there. You can follow my code below, which works fine as per my test:
Note: in the filter, the column name is case-sensitive.
CloudTableClient tableClient = storageAccount.CreateCloudTableClient();
CloudTable table = tableClient.GetTableReference("test1");
string propNullCondition = TableQuery.GenerateFilterConditionForInt(
"prop1", //note the column name shoud be case-sensitive here.
QueryComparisons.GreaterThanOrEqual,
-1);
propNullCondition = $"{TableOperators.Not}({propNullCondition})";
TableQuery<DynamicTableEntity> propNotEqualValueCondition = new TableQuery<DynamicTableEntity>()
.Where(
TableQuery.CombineFilters(
propNullCondition,
TableOperators.Or,
TableQuery.GenerateFilterConditionForInt(
"prop1",//note the column name shoud be case-sensitive here.
QueryComparisons.NotEqual,
2)));
var query = table.ExecuteQuery(propNotEqualValueCondition);
foreach (var q in query)
{
Console.WriteLine(q.PartitionKey);
}
The test result:
Here is my table in azure:
I have a database with a json field which has multiple parts including one called tags, there are other entries as below but I want to return only the fields with "{"tags":{"+good":true}}".
"{"tags":{"+good":true}}"
"{"has_temps":false,"tags":{"+good":true}}"
"{"tags":{"+good":true}}"
"{"has_temps":false,"too_long":true,"too_long_as_of":"2016-02-12T12:28:28.238+00:00","tags":{"+good":true}}"
I can get part of the way there with this statement in my where clause trips.metadata->'tags'->>'+good' = 'true' but that returns all instances where tags are good and true including all entries above. I want to return entries with the specific statement "{"tags":{"+good":true}}" only. So taking out the two entries that begin has_temps.
Any thoughts on how to do this?
With jsonb column the solution is obvious:
with trips(metadata) as (
values
('{"tags":{"+good":true}}'::jsonb),
('{"has_temps":false,"tags":{"+good":true}}'),
('{"tags":{"+good":true}}'),
('{"has_temps":false,"too_long":true,"too_long_as_of":"2016-02-12T12:28:28.238+00:00","tags":{"+good":true}}')
)
select *
from trips
where metadata = '{"tags":{"+good":true}}';
metadata
-------------------------
{"tags":{"+good":true}}
{"tags":{"+good":true}}
(2 rows)
If the column's type is json then you should cast it to jsonb:
...
where metadata::jsonb = '{"tags":{"+good":true}}';
If I get you right, you can check text value of the "tags" key, like here:
select true
where '{"has_temps":false,"too_long":true,"too_long_as_of":"2016-02-12T12:28:28.238+00:00","tags":{"+good":true}}'::json->>'tags'
= '{"+good":true}'
I have list A with three columns JobNumber,Crew and Date which is lookup column to List B. When I create three individual lookup fields in List B then following code works fine,
SP.FieldLookupValue lvjobNum = new SP.FieldLookupValue();
lvjobNum.LookupId = ID;
lItem["JobNumber"] = lvjobNum;
SP.FieldLookupValue lvCrew = new SP.FieldLookupValue();
lvCrew.LookupId = ID;
lItem["Crew"] = lvCrew;
SP.FieldLookupValue lvDate = new SP.FieldLookupValue();
lvDate.LookupId = ID;
lItem["Date"] = lvDate;
However when I create lookup field using "Additional column settings" option like,
Then same code shown above doesn't work and it throws an error,
<nativehr>0x80070057</nativehr><nativestack></nativestack>Invalid data has been used to update the list item. The field you are trying to update may be read only.
Any idea ?

Fix was simple,

I am new to sharepoint, I have a custom field type derived from SpFieldChoice , my field allows users to select multiple values, I have a requirement of replacing some old custom columns with the new column and copy the data in old column to the new column. the old column also allows the users to select multiple values by ticking checkboxes, I have the following code to copy the data to new field.
foreach (SPListItem item in list.Items)
{
if (item[oldField.Title] == null)
{
item[newFld.Title] = string.Empty;
item.Update();
}
else
{
string[] itemvalues = item[oldField.Title].ToString().Split(new string[] {";#"}, StringSplitOptions.None);
StringBuilder multiLookupValues = new StringBuilder();
multiLookupValues.Append(";#");
for (int cnt = 0; cnt < (itemvalues.Length) / 2; cnt++)
{
multiLookupValues.Append (itemvalues[(cnt * 2) + 1].ToString() + ";#");
}
item[newFld.Title] = multiLookupValues.ToString();
item.SystemUpdate(false) ;
}
}
This code works fine until the length of resulting stringbuilder is less than 255 charachters , but when this length is greater then 255 I get the following Exception.
Invalid choice Value. A choice field contains invalid data.Please check the value and try again.
Is there any other way of copying data to SpFiledChoice, How can I resolve this problem? please help me.
Do the update multiple times so that the string doesn't exceed - i.e. value +=. However, if the problem is that the value can't be longer that 255, you have to consider how you are doing the choices. If it is exceeding the length and updating the value multiple times doesn't work (and a Site Column will have the same limitations), you can do the next best thing:
1) Create a new list that will hold the choices
2) Change the destination field to be a lookup
3) Update accordingly for each item (picking up the ID from the lookup field)
There's no limit to this.

This is my sql command:
select INCOME_TYPE_ID,

and I got this error:
Ambiguous Columns Defined
I'm Using SQL Developer as Oracle client.
Apparently one (or more) column names in your select list exists in more than one table of the FROM list.
You need to prefix every column in the SELECT list with the table it's coming from (it's also a good practice to always do that, regardless of the fact if they are ambigous)
Mention name of table before every column in select query.
Ambiguous column means that you have more than one column with the same name in one of the SELECT statements.
Try this instead, prefgixing all selected columns with their fully qualified names (as you have done elsewhere in your SELECT):
select INCOME.INCOME_TYPE.INCOME_TYPE_ID,
COMMON.REGION.REGION_CODE,
ACCOUNTING.FIN_YEAR.FIN_YEAR_CODE,
ACCOUNTING.VOUCHER_ITEM_RECEIVE_DOC.PORTION_AMOUNT
from INCOME.INCOME_TYPE,
COMMON.REGION,
INCOME.RECEIVE_DOC_PORTION,
INCOME.ASSESS_ORDER_ITEM,
ACCOUNTING.VOUCHER_ITEM_RECEIVE_DOC,
ACCOUNTING.VOUCHER_ITEM,
ACCOUNTING.VOUCHER,
ACCOUNTING.FIN_YEAR
where INCOME.RECEIVE_DOC_PORTION.ASSESS_ORDER_ITEM_ID = INCOME.ASSESS_ORDER_ITEM.ASSESS_ORDER_ITEM_ID
and INCOME.ASSESS_ORDER_ITEM.INCOME_TYPE_ID = INCOME.INCOME_TYPE.INCOME_TYPE_ID
and INCOME.RECEIVE_DOC_PORTION.RECEIVE_DOC_PORTION_ID = ACCOUNTING.VOUCHER_ITEM_RECEIVE_DOC.RECEIVE_DOC_PORTION_ID
and ACCOUNTING.VOUCHER_ITEM_RECEIVE_DOC.VOUCHER_ITEM_ID = ACCOUNTING.VOUCHER_ITEM.VOUCHER_ITEM_ID
and ACCOUNTING.VOUCHER_ITEM.VOUCHER_ID = ACCOUNTING.VOUCHER.VOUCHER_ID
and ACCOUNTING.VOUCHER.REGION_CODE = COMMON.REGION.REGION_CODE
and ACCOUNTING.VOUCHER.FIN_YEAR_CODE = ACCOUNTING.FIN_YEAR.FIN_YEAR_CODE
I had to guess the filly qualified name for
ACCOUNTING.VOUCHER_ITEM_RECEIVE_DOC.PORTION_AMOUNT
It might be
INCOME.RECEIVE_DOC_PORTION.PORTION_AMOUNT
But you should be able to resolve that easily.
Hope it helps...
