Descripción:

|
||
En comparación con otros lenguajes de programación, T-SQL no es un lenguaje difícil de
|
||
aprender, y al neto de cualquier
|
||
error sintáctico puede ser muy tolerante. Sin embargo, tendemos a aprender solo las
|
||
declaraciones fundamentales del
|
||
lenguaje: SELECT, INSERT, UPDATE e DELETE; solo aquellos que invierten más tiempo,
|
||
descubren la naturaleza declarativa
|
||
de este lenguaje y pueden obtener el máximo rendimiento y poder de sus
|
||
consultas(querys).
|
||
Este worlshop proporciona una introducción a los Planes de Ejecución y los DMV en SQL
|
||
Server, trata en modo detallado
|
||
las statement set-based presentes en el lenguaje T-SQL. Los Planes de ejecución nos
|
||
ayudan a responder a las preguntas:
|
||
"¿Por qué esta query es tan lenta?", "¿Qué índices se utilizan y cómo?". Los DMV
|
||
(vistas y funciones del sistema)
|
||
proporcionan información sobre el estado de salud de la instancia de SQL Server, así
|
||
como un interesante
|
||
feedback sobre el rendimiento de las querys. Los temas tratados sobre el lenguaje T-SQL
|
||
permitirán mejorar la escritura
|
||
del código, explotando las statement set-based presentes durante algún tiempo en SQL
|
||
Server, así como las implementadas
|
||
en las últimas versiones, con referencia particular a las funciones de Windows.
