I am having problem in updating database from xml and dynamic query.
Exec('UPDATE ' + #DbInstance + 'dbo.tblAcademic
SET tblacademic.RollNo = XMLAcademic.Item.value(''#RollNo'', ''VARCHAR(50)''),
tblacademic.Board = XMLAcademic.Item.value(''#Board'', ''VARCHAR(150)''),
tblacademic.PassingYear = XMLAcademic.Item.value(''#PassingYear'', ''VARCHAR(10)''),
tblacademic.Semester = XMLAcademic.Item.value(''#Semester'', ''VARCHAR(5)''),
tblacademic.MarksObt = XMLAcademic.Item.value(''#MarksObt'', ''varchar(9)''),
tblacademic.MaxMarks = XMLAcademic.Item.value(''#MaxMarks'', ''int'')
FROM ''' + Convert(varchar, #XMLEducationalDetail) + '''.nodes(''/root/row'') AS XMLAcademic(Item)
WHERE tblacademic.AcademicID = XMLAcademic.Item.value(''#AcademicID'', ''int'')')
This is showing error at Convert function and without convert function there is also execution error showing xml to nvarchar error.

I am trying to populate a column that is to represent an Internal URL that directs the user to a specific document. The document ID, DOC_ID, is already populated in the Table. I would like to populate the column by prepending a base URL to the Document ID. I do not know how to to do this dynamically and am getting some errors referring to the parameters of CONCAT(), issue being it is understanding it to be a string rather than the column value. My code is as follows:
SET #Insert_DRS_URL_SQL = 'UPDATE'
+ ' '
+ QUOTENAME(#TBL)
+ ' '
+ 'SET DRS_URL = CONCAT(#URLBASE'
+ ','
+ 'DOC_ID'
+ ')'
EXECUTE sp_executesql #Insert_DRS_URL_SQL;
UPDATE
#URLBASE = 'http://blah/blah/blah/id='
DRS_URL is the column I wish to populate.
Basically I need DRS_URL = #BASEURL + DOC_ID
While the normal Select statements used on R are fetching the data, I am not able to fetch the data using SQL on the following query:
The SQL part is working on SQL Server 2008. Also, I am using RStudio
Any suggestions what is wrong here?
qf<-sqlQuery(mycon,"USE MDM_STAT

+ DECLARE #RUNYEAR INT;
+ DECLARE #PERIOD INT;

I suggest you to follow the following steps:
1) You should make sure the the connection string is set correctly for establishing the correct connection with the database.
a quite good explanation appears here: short youtube tutorial
2) in R write:
library(RODBC)
channel = odbcConnect("The_database_name_your_are_connecting_to")
...
sqlQuery(channel ,"your query here")
close(channel)
I suggest you to start with the simplest query and after you made sure it worked,
go with a more complex query
hope it would work for you, good luck!
In the oracle database there is a schema. Inside schema there is a package which contains different methods. How to retrieve the metadata of the procedure using getProcedureColumn() function in DatabaseMetaDataclass?
I have tried to get metadata using getProcedureColumns(catalog,schemaname,procedurename,columnnamepattern) it works fine when the procedure is located inside a schema. When a procedure is located inside a package in a schema it is not retrieving.
This will print out all the column information for a specific procedure in a package. Change parameters with real values.
DriverManager.registerDriver(new oracle.jdbc.driver.OracleDriver());
Connection conn =
DriverManager.getConnection ("jdbc:oracle:thin:#<server>:<port>:<sid>", "<username>", "<password>");
DatabaseMetaData metadata = conn.getMetaData();
String packageName = "<your package name>";
String schemaName = "<schema name>";
String procedureName = "<procedure name>";
ResultSet rs = metadata.getProcedureColumns(
packageName,
schemaName,
procedureName,
"%");
while(rs.next()) {
// get stored procedure metadata
String procedureCatalog = rs.getString(1);
String procedureSchema = rs.getString(2);
procedureName = rs.getString(3);
String columnName = rs.getString(4);
short columnReturn = rs.getShort(5);
int columnDataType = rs.getInt(6);
String columnReturnTypeName = rs.getString(7);
int columnPrecision = rs.getInt(8);
int columnByteLength = rs.getInt(9);
short columnScale = rs.getShort(10);
short columnRadix = rs.getShort(11);
short columnNullable = rs.getShort(12);
String columnRemarks = rs.getString(13);
System.out.println("stored Procedure name="+procedureName);
System.out.println("procedureCatalog=" + procedureCatalog);
System.out.println("procedureSchema=" + procedureSchema);
System.out.println("procedureName=" + procedureName);
System.out.println("columnName=" + columnName);
System.out.println("columnReturn=" + columnReturn);
System.out.println("columnDataType=" + columnDataType);
System.out.println("columnReturnTypeName=" + columnReturnTypeName);
System.out.println("columnPrecision=" + columnPrecision);
System.out.println("columnByteLength=" + columnByteLength);
System.out.println("columnScale=" + columnScale);
System.out.println("columnRadix=" + columnRadix);
System.out.println("columnNullable=" + columnNullable);
System.out.println("columnRemarks=" + columnRemarks);
}
This is the code i written but i am unable to view the data what's wrong can any one tell
conn_obj.Connect();
SQL = "SELECT FIELDNAME BS_FIELDF WHERE FK_TABDF = '";
SQL = SQL + Table_pkey + "' ORDER BY FIELDNAME";
dSet = conn_obj.SQL_Data_Retrieve(SQL.ToString(), "BS_FIELDF");
conn_obj.DisConnect();
MainTableGrid.AutoGenerateColumns = true; // Added now....
Bind_DataGridView.DataSource = dSet.Tables[0];
MainTableGrid.DataSource = Bind_DataGridView.DataSource;
MainTableGrid.Refresh();
MainTableGrid.Parent.Refresh();
Are you getting data back from your query?
If not add a comma between FIELDNAME and BS_FIELDF in your SQL statement.
where a.system_nr =''''5300'''' and
a.external_status_cd = '''''''' and
a.cust_acct_id = b.rel_cust_acct_id and
b.cust_acct_id = c.cust_acct_id and
c.cust_acct_id = d.cust_acct_id and
d.acct_status_cd = ''''OPEN'''' and
d.time_mnth_gen_id =''''' + #BegDate + ''''' and
a.cust_acct_id = e.cust_acct_id and
e.tran_dt >=''''' + #BegDate + ''''' and
e.tran_dt<=''''' + #EndDate + ''''' and
d.portfolio_cd = ''''HEQ'''' and
a.time_mnth_gen_id =''''' + #BegDate + ''''' '')'
Here is the where condition which is already written and I need to make changes.
Can you please tell me why they are using '''''+#begdate'''''? Can i use '+Bedate'?
I mean why they are using ''''' each side?
Try this in SQL Server:
select '''''someval'''''
You notice that item gives:
''someval''
In SQL Server '' will equate to a single quote character, so the above line is
select [open string][single quote][single quote]someval[single quote][single quote][close string]
Without seeing the rest of the SQL, my guesses would be:
for use in dynamic SQL as #BegDate is a variable and you have the statement ending with a single quote
the data contains a bunch of single quotes
You should not be able to just '+BegDate' because it's a variable and stripping the # would cause it to be evaluated as a field.
If you meant to just reduce the number of single quotes, I would imagine the original author put them there for a reason. You can run the query with the original single quotes and again with the reduced single quotes and see if you get the same result set.
