On the client or server computer. LOCOPY FunctionThe LOCOPY function creates a copy of a smart large object. The first parameter specifies the BLOB or CLOB column to copy. The table name and column name parameters are optional:If you omit table name and column name, the LOCOPY function creates a smart large object with system-specified storage defaults and copies the data in the BLOB or CLOB column into it. It obtains the system-specific storage defaults from either the ONCONFIG file or the sbspace. For more information on system-specified storage defaults, see the INFORMIX-Universal Server Administrator's Guide.When you specify a table name and column name, the LOCOPY function uses the storage characteristics from the specified column name for the BLOB or CLOB value that it creates.The LOCOPY function returns a handle value (a pointer) to the new BLOB or CLOB value. This function does not actually store the new smart-large-object value into a column in the database. You must assign the BLOB or CLOB value to the appropriate column.The following ESQL/C code fragment copies the CLOB value in the resume column of the candidate table to the resume column of the interview table:/* Insert a new row in the interview table and get the * resulting SERIAL value (from sqlca.sqlerrd[1]) */EXEC SQL insert into interviews (intrv_num, intrv_time) values (0, '09:30');intrv_num = sqlca.sqlerrd[1];/* Update this interview row with the candidate number * and resume from the candidate table. Use LOCOPY to * create a copy of the CLOB value in the resume

How to show CLOB type in a SELECT in SQL Server?

Handle value share the CLOB or BLOB value across several columns. This storage arrangement reduces the amount of disk space that the CLOB or BLOB data takes. However, when several columns share the same smart-large-object value, the following conditions result:The chance of lock contention on a CLOB or BLOB column increases. If two columns share the same smart-large-object value, the data might be locked by either column that needs to access it. The CLOB or BLOB value can be updated from a number of pointsTo remove these constraints, you can create separate copies of the BLOB or CLOB data for each column that needs to access it. You can use the LOCOPY function to create a copy of an existing smart large object. You can also use the SQL functions LOTOFILE, FILETOCLOB, and FILETOBLOB to access smart-large-object values. For more information on these functions, see "Smart-Large-Object Functions". For more information on the BLOB and CLOB data types, see Chapter 2 of the Informix Guide to SQL: Syntax. Constant Expressions The following diagram shows the possible syntax for constant expressions. ElementPurposeRestrictionsSyntaxdatetime unitOne of the units that is used to specify an interval precision; that is, YEAR, MONTH, DAY, HOUR, MINUTE, SECOND, or FRACTION. If the unit is YEAR, the expression is a year-month interval; otherwise, the expression is a day-time interval.The datetime unit must be one of the keywords that is listed in the Purpose column. You can enter the keyword in uppercase or lowercase letters. You cannot put quotation marks

Column * of the candidate table. */EXEC SQL update interviews SET (cand_num, resume) = (SELECT cand_num, LOCOPY(resume, 'candidate', 'resume') FROM candidate WHERE cand_lname = 'Haven') WHERE intrv_num = :intrv_num;In the preceding example, the LOCOPY function returns a handle value for the copy of the CLOB resume column in the candidate table. Because the LOCOPY function specifies a table and column name, this new CLOB value has the storage characteristics of this resume column. If you omit the table ('candidate') and column ('resume') names, the LOCOPY function uses the system-defined storage defaults for the new CLOB value. The UPDATE statement then assigns this new CLOB value to the resume column in the interviews table.

CLOB value to the appropriate column.GLSThe FILETOCLOB function performs any code-set conversion that might be required when it copies the file from the client or server computer to the database. The following INSERT statement uses the FILETOCLOB function to create a CLOB value from the value in the haven.rsm file:INSERT INTO candidate (cand_num, cand_lname, resume) VALUES (0, 'Haven', FILETOCLOB('haven.rsm', 'client'))In the preceding example, the FILETOCLOB function reads the haven.rsm file in the current directory on the client computer and returns a handle value to a CLOB value that contains the data in this file. Because the FILETOCLOB function does not specify a table and column name, this new CLOB value has the system-specified storage characteristics. The INSERT statement then assigns this CLOB value to the resume column in the candidate table. LOTOFILE FunctionThe LOTOFILE function copies a smart large object to an operating-system file. The first parameter specifies the BLOB or CLOB column to copy. The function determines the operating-system file to create from the following parameters:The pathname parameter identifies the directory path and name of the source file.The file destination parameter identifies the computer, client or server, on which this file resides:Set file destination to 'client' to identify the client computer as the location of the source file. The pathname can be either a full pathname or relative to the current directory.Set file destination to 'server' to identify the server computer as the location of the source file. The pathname must be a full pathname.By default, the LOTOFILE function

Similarly, the FILETOCLOB function creates a CLOB value for data that is stored in an operating-system file. These functions determine the operating-system file to use from the following parameters:The pathname parameter identifies the directory path and name of the source file.The file destination parameter identifies the computer, client or server, on which this file resides:Set file destination to "client" to identify the client computer as the location of the source file.

Function. Using Smart Large ObjectsThe SELECT, UPDATE, and INSERT statements do not manipulate the values of smart large objects directly. Instead, they use a handle value, which is a type of pointer, to access the BLOB or CLOB value, as follows:The SELECT statement returns a handle value to the BLOB or CLOB value that the select list specifies.SELECT does not return the actual data for the BLOB or CLOB column that the select list specifies. Instead, it returns a handle value to the column data.The INSERT and UPDATE statements accept a handle value for a BLOB or CLOB to be inserted or updated.INSERT and UPDATE do not send the actual data for the BLOB or CLOB column to the database server. Instead, they accept a handle value to this data as the column value. To access the data of a smart-large-object column, you must use one of the following application programming interfaces (APIs):From within an INFORMIX-ESQL/C program, use the ESQL/C library functions that access smart large objects.For more information, see the INFORMIX-ESQL/C Programmer's Manual.From within a C program such as a DataBlade module, use the Client and Server API.For more information, see your DataBlade Developers Kit User's Guide.You cannot use the name of a smart-large-object column in expressions that involve arithmetic operators. For example, operations such as addition or subtraction on the smart-large-object handle value have no meaning. When you select a smart-large-object column, you can assign the handle value to any number of columns: all columns with the same.

What is the difference between CLOB and NCLOB?

Generates a filename of the form:file.hex_idIn this format, file is the filename you specify in pathname and hex_id is the unique hexadecimal smart-large-object identifier. The maximum number of digits for a smart-large-object identifier is 17; however must smart large objects would have an identifier with significantly fewer digits.For example, suppose you specify a pathname value as follows:'/tmp/resume'If the CLOB column has an identifier of 203b2, the LOTOFILE function would create the file:/tmp/resume.203b2To change this default filename, you can specify the following wildcards in the filename of the pathname:One or more contiguous question mark (?) characters in the filename can generate a unique filename. The LOTOFILE function replaces each question mark with a hexadecimal digit from the identifier of the BLOB or CLOB column. For example, suppose you specify a pathname value as follows:'/tmp/resume??.txt'The LOTOFILE function puts 2 digits of the hexadecimal identifier into the name. If the CLOB column has an identifier of 203b2, the LOTOFILE function would create the file:/tmp/resume20.txtIf you specify more than 17 question marks, the LOTOFILE function ignores them.An exclamation point (!) at the end of the filename indicates that the filename does not need to be unique.For example, suppose you specify a pathname value as follows:'/tmp/resume.txt!'The LOTOFILE function does not use the smart-large-object identifier in the filename so it generates the following file:/tmp/resume.txtIf the filename you specify already exists, LOTOFILE returns an error.GLSThe LOTOFILE function performs any code-set conversion that might be required when it copies a CLOB value from the database to a file.
